| Statistical Mechanics Seminar | |
| Topic: | Local Density Fluctuations, Hyperuniformity, and Order Metrics |
| Presenter: | Salvatore Torquato, Princeton University |
| Date: | Wednesday, November 3, 2004, Time: 2:00 p.m., Location: Jadwin 343 |
| Abstract: | We study the variance in the number of points contained within a window of arbitrary size in space dimension d, and further illuminate our understanding of "hyperuniform" systems, i.e., point patterns that do not possess infinite-wavelength fluctuations. For large windows, hyperuniform systems are characterized by a local variance that grows only as the surface area (rather than the volume) of the window. We show that hyperuniform systems are at a ``critical-point'' of a type with appropriate scaling laws and critical exponents. We show that finding the global minimum of the local variance is equivalent to determining the ground state of a certain system of interacting particles, which in turn is related to a problem in number theory. We prove that the simple periodic linear array yields the global minimum value of the average variance among all infinite one-dimensional hyperuniform patterns. Contrary to the conjecture that the lattices associated with the densest packing of congruent spheres have the smallest variance regardless of the space dimension, we show that for d=3, the body-centered cubic lattice has a smaller variance than the face-centered cubic lattice. |

| Topic: | Quantum product and the intermediate Jacobian |
| Presenter: | Thomas Graber, Berkeley |
| Date: | Wednesday, November 3, 2004, Time: 3:00 p.m., Location: Fine Hall 214 |
| Abstract: | I will discuss joint work with R. Pandharipande which addresses two questions about the genus zero Gromov-Witten theory of the cubic threefold. First, we study the Gromov-Witten invariants involving the odd cohomology. Second, we study the quantum product on the Chow ring. These questions are related in that both can be interpreted in terms of the geometry of the intermediate Jacobian and the Abel-Jacobi map. |
| Special Seminar on Computer Algebra | |
| Topic: | A status report on GRTensor |
| Presenter: | Kayll Lake, Queen's University at Kingston |
| Date: | Wednesday, November 3, 2004, Time: 3:00 p.m., Location: Jadwin A03 |
| Abstract: | GRTensor is now a mature and widely used tool for performing abstract calculations in the general area of differential geometry. The package, which runs under Maple and Mathematica, contains a library of standard definitions of a large number of commonly used curvature tensors, as well as the Newman-Penrose formalism. The standard object libraries are easily expandable by a facility for defining new tensors. Calculations can be carried out in spaces of arbitrary dimension (for example, an explicit global covering of the Schwarzschild-Tangherlini black holes in all dimensions D>4 will be given) and in multiple spacetimes simultaneously. Live demonstrations will include some recent developments on interactive databases of exact solutions (applied to both research and teaching) and the problem of visualization associated with the study of spacetime invariants (for example the evolution of differential invariants in the Kerr spacetime). Sponsored by the Gravity and String Theory Groups. |

| Topology Seminar | |
| Topic: | Deformation theory of hyperbolic 3-manifolds |
| Presenter: | Dick Canary, University of Michigan and Wesleyen |
| Date: | Thursday, November 4, 2004, Time: 4:30 p.m., Location: Fine Hall 314 |
| Abstract: | We will survey recent results concerning the space $AH(M)$ of all hyperbolic 3-manifolds homotopy equivalent to a fixed compact 3-manifold $M$. The recent resolution of Thurston's Ending Lamination Conjecture provides a classification of the manifolds in $AH(M)$ in terms of topological data, the marked homeomorphism type of the manifold, and geometric data, which encodes the asymptotic geometry of the ends of the manifold. However, these invariants vary discontinuously over $AH(M)$ and the topology of $AH(M)$ has been found to be much more complicated than expected. |

| Analysis Seminar | |
| Topic: | Global well-posedness for the Klein-Gordon-Schrodinger system below the energy space |
| Presenter: | Nikolaos Tzirakis, IAS and University of Toronto |
| Date: | Monday, November 8, 2004, Time: 3:00 p.m., Location: Fine Hall 314 |
| Abstract: | I will show that the Klein-Gordon-Schrodinger system in one,two, and three dimensions, has a global solution below the energy space. These type of equations, in the continuum and in a spatially discrete form, are relevant to a variety of physical applications including studies of the DNA double strand and models of polarons among others. The proof uses the "I-method" recently introduced by J. Colliander, M. Keel, G. Staffilani, H. Takaoka and T.Tao, and mixed type Strichartz estimates for the solutions of Schrodinger and Klein-Gordon equation respectively. In every different case/dimension a new local well posedness result has to be proved in order to take advantage of the decay of the "modify energy" that the "I-method" introduces. |

| Presenter: | Ronald Coifman, Department of Mathematics, Yale University |
| Date: | Monday, November 8, 2004, Time: 4:00 p.m., Location: Fine Hall 214 |
| Abstract: | We will discuss simple methodologies for analyzing and discovering geometric structures in massive data sets. We introduce multiscale Harmonic analysis on graphs and on subsets of Euclidean spaces. The methods augment spectral graph theory, kernel principal component analysis, manifold learning and other methods from machine learning. |
| Joint Princeton University and Institute for Advanced Study Number Theory Seminar | |
| Topic: | Elliptic curves and skew-Hermitian matrices |
| Presenter: | Karl Rubin, Univ. California at Irvine |
| Date: | Monday, November 8, 2004, Time: 4:30 p.m., Location: Fine Hall 322 |
| Abstract: | Suppose E is an elliptic curve defined over a number field K, and p is a prime where E has good ordinary reduction. The usual methods of Iwasawa theory give a single Iwasawa module from which one can recover the Selmer groups of E over all finite extensions of K in a Z_p^d-extension. These Selmer groups come with important parings: the Cassels pairing on the Tate-Shafarevich group and the p-adic height pairing on the Mordell-Weil group. In joint work with Barry Mazur we show that (under mild hypotheses) there is a free Iwasawa module with a skew-Hermitian pairing (unique up to isomorphism) from which one can recover not only the Selmer groups over all intermediate fields but all of the pairings as well. In this talk I will explain this result and give some examples. |
| Algebraic Geometry Seminar | |
| Topic: | Canonical cooridinates on leaves |
| Presenter: | C.-L. Chai, University of Pennsylvania |
| Date: | Tuesday, November 9, 2004, Time: 4:30 p.m., Location: Fine Hall 322 |
| Abstract: | Let $k$ be an algebraically closed field of characteristic $p>0$. A leaf $C$ in the Siegel modular variety $\cal A_g$, as defined by Oort, is the locus defined by a fixed isomorphism type of polarized Barsotti-Tate group. Let $x_0$ be a closed point of $C$. It turns out that the formal completion $C^{/x_0}$ of $C$ at $x_0$ is "built up" from $p$-divisible formal groups, by a system of fibrations. This is a generalization of the Serre-Tate coordinates for the local moduli space of an ordinatry abelian variety, and plays an important role in the proof (with Oort) of the Hecke orbit conjecture. |
| Statistical Mechanics Seminar | |
| Topic: | Bosons in disc-shaped traps |
| Presenter: | Jakob Yngvason, University of Vienna |
| Date: | Wednesday, November 10, 2004, Time: 2:00 p.m., Location: Jadwin 343 |
| Abstract: | Recently it has become possible to produce dilute Bose gases in traps that confine the particle motion strongly in one or two directions so that the system becomes effectively lower dimensional. A rigorous derivation of the low-dimensional behavior from the many-body Hamiltonian of a three-dimensional gas is not a simple problem, however, because the ground state wave function can generally not be approximately factorized in the longitudinal and transverse variables. In the lecture the dimensional reduction from 3D to 2D in thin, disk-shaped traps will be discussed. |

| Geometry, Representation Theory, and Moduli Seminar | |
| Topic: | Amoebas and algebraic dynamic |
| Presenter: | Manfred Einsiedler, Princeton University |
| Date: | Wednesday, November 10, 2004, Time: 3:00 p.m., Location: Fine Hall 214 |
| Abstract: | I will describe how amoebas help to describe the dynamical properties of $\mathbb Z^d$-actions by automorphisms of compact abelian groups, and give concrete examples for that connection. One property, that is best characterized by the amoeba, is expansiveness of subactions. A $\mathbb Z^k$-subaction is expansive if there exists an $\epsilon>0$ such that there are not two points $x\neq y$ that stay $\epsilon$-close forever (for the $\mathbb Z^k$-action). |
| Department Colloquium | |
| Topic: | The Sharp Form of the Strong Szego Theorem |
| Presenter: | Barry Simon, Caltech |
| Date: | Wednesday, November 10, 2004, Time: 4:30 p.m., Location: Fine Hall 314 |
| Abstract: | This talk will discuss a proof of the Strong Szego theorem on the second term in the asymptotics of Toeplitz determinants. After a brief discussion of the history, I'll discuss the elementary argument that reduces the sharp (optimal) result to the case of analytic symbols. I'll then present a new proof of the theorem in the analytic case. I'll present the necessary background from the theory of orthogonal polynomials on the unit circle along the way. |
| Ergodic Theory and Statistical Mechanics Seminar | |
| Topic: | Random matrices, statistical mechanics and hyperbolic symmetry breaking |
| Presenter: | Thomas Spencer, Institute for Advanced Study |
| Date: | Thursday, November 11, 2004, Time: 2:00 p.m., Location: Fine Hall 322 |
| Abstract: | We explain how fluctuations of a lattice field theory with hyperbolic symmetry SU(1,1) arise naturally from the study of certain random band matrix ensembles. These ensembles are related to GUE but incorporate an additional spatial structure. If the lattice dimension is 3 or more, we prove that this symmetry is broken so that moments of the field are bounded in the infinite volume limit. Implications for the band random matrix ensembles are discussed. The key ingredients of our proof are the use of horospherical coordinates and Brascamp-Lieb inequalities. This is joint work with Martin Zirnbauer. |
| Joint Analysis Seminar | |
| Topic: | Asymptotically simple solutions of the vacuum Einstein equations in even dimensions |
| Presenter: | Michael Anderson, SUNY at Stonybrook |
| Date: | Thursday, November 11, 2004, Time: 3:30 p.m., Location: Fine Hall 214 |
| Abstract: | We will discuss a new construction of space-times in the title with $\Lambda > 0$ or $\Lambda = 0$ based on solving the Cauchy problem for a conformally invariant system of equations formed from the Fefferman-Graham (ambient obstruction) tensor. |
| Topology Seminar | |
| Topic: | Shrinkwrapping and the Taming of Hyperbolic 3-Manifolds |
| Presenter: | David Gabai , Princeton University |
| Date: | Thursday, November 11, 2004, Time: 4:30 p.m., Location: Fine Hall 314 |
| Abstract: | We show that if N is a complete hyperbolic 3-manifold with finitely generated fundamental group, then N is the interior of a compact 3-manifold; thereby obtaining a positive proof of the "Marden Conjecture" also known as the "Tameness Conjecture" (Also proven by Ian Agol). A key ingredient is Shrinkwrapping which is a method for producing surfaces of intrinsic curvature ¾-1. We will discuss some of its many applications to hyperbolic geometry and 3-manifold topology. (This is joint work with Danny Calegari). |

| Analysis Seminar | |
| Topic: | A singular energy minimizing free boundary |
| Presenter: | Daniela De Silva, MIT |
| Date: | Monday, November 15, 2004, Time: 3:00 p.m., Location: Fine Hall 314 |
| Abstract: | In this talk, we will exhibit the first example of a singular energy minimizing free boundary. This example occurs is dimension 7, which is conjectured to be the optimal dimension for free boundary regularity. This is analogous to the 8-dimensional Simons cone, in the theory of minimal surfaces. We will highlight the similarities between the two theories, explaining how the proof of the minimality of the Simons cone, was the inspiration for our proof. This is a joint work with David Jerison. |
| PACM Seminar | |
| Topic: | Astrophysical Gas Dynamics |
| Presenter: | Jim Stone, Department of Astrophysical Sciences, Princeton University |
| Date: | Monday, November 15, 2004, Time: 4:00 p.m., Location: Fine Hall 214 |
| Abstract: | Most of the visible matter in the Universe is a plasma, that is a dilute gas of electrons, ions, and neutral particles. In many cases the dynamics of this plasma is described to a good approximation by the equations of compressible hydrodynamics, magneto-hydrodynamics (in the case that magnetic fields are present), or radiation MHD (in the case that photons provide significant energy or momentum transport). Studying multidimensional, time-dependent and/or highly nonlinear processes in astrophysical plasmas usually requires numerical methods, however developing accurate and robust methods for compressible MHD and/or radiation MHD is still an active area of research in applied mathematics. I will describe some problems in astrophysics which motivate the development of such methods, describe recent advance in numerical algorithms for MHD and their implementation on parallel processors, and describe some of what we have learned from application of the methods. |

| Topic: | Mirror symmetry for weighted projective planes and their noncommutative deformations |
| Presenter: | Dmitri Orlov, Institute for Advanced Study |
| Date: | Wednesday, November 17, 2004, Time: 3:00 p.m., Location: Fine Hall 214 |
| Abstract: | The derived categories of coherent sheaves of weighted projective spaces and their noncommutative deformations will be described. We explain how the homological mirror symmetry conjecture looks for the weighted projective planes and show that it holds in this case. Moreover, we also show that this mirror correspondence between derived categories can be extended to toric noncommutative deformations of a weighted projective planes where B-branes are concerned, and their mirror counterparts, non-exact deformations of the symplectic structure of the Landau-Ginzburg where A-branes are concerned. |
| Joint Analysis Seminar | |
| Topic: | A deterministic control based approach to motion by curvature. |
| Presenter: | Sylvia Serfaty, Courant Institute |
| Date: | Thursday, November 18, 2004, Time: 3:30 p.m., Location: Fine Hall 214 |
| Abstract: | In a joint work with Bob Kohn, we give a new control-type interpretation on the level-set approach to motion by curvature and related interface motion laws. More precisely, we give a family of discrete-time, two-person games whose value functions converge in the continuous-time limit to the solution of the motion-by-curvature PDE. The value function of a deterministic control problem is normally a first-order Hamilton-Jacobi equation, while the level-set formulation of motion by curvature is a second-order parabolic equation. |
| Geometric Analysis Seminar | |
| Topic: | On the Genus-One Gromov-Witten Invariants of Complete Intersection Threefolds |
| Presenter: | Aleksey Zinger, Stanford University |
| Date: | Friday, November 19, 2004, Time: 4:00 p.m., Location: Fine Hall 314 |
| Abstract: | I will describe a formula relating the genus-one Gromov-Witten invariants of a projective complete intersection threefold to the GW-invariants of the ambient projective space. Along with a separate desingularization result, this formula allows one to compute the genus-one GW-invariants of such threefolds. It might be possible to use this formula to verify the genus-one mirror symmetry prediction for curves in Calabi-Yau threefolds |

| Topic: | Qualitative/Quantitative Analysis of a Class of Biological Networks |
| Presenter: | Eduardo Sontag, Department of Math and BioMaPS Institute for Quantitative Biology, Rutgers University |
| Date: | Monday, November 22, 2004, Time: 4:00 p.m., Location: Fine Hall 214 |
| Abstract: | The analysis of signaling networks constitutes one of the central questions in systems biology: there is an pressing need for powerful mathematical tools to help understand, quantify, and conceptualize their information processing and dynamic properties. Approaches based upon detailed modeling and simulation are hampered by the fact that is virtually impossible to experimentally validate the form of the nonlinearities used in reaction terms, or, even when such forms are known, to accurately estimate coefficients (parameters). In this presentation, we show how some signaling systems may be profitably studied by first decomposing them into several subsystems, each of which is endowed with certain "qualitative" mathematical properties. These properties, in conjunction with a relatively small amount of "quantitative" data, allow the behavior of the entire, reconstituted system, to be deduced from the behavior of its parts. This novel approach emerged originally from our study of possible multi-stability or oscillations in feedback loops in cell signal transduction modeling, but turns out to be of more general applicability. (Most of the work reported in this talk was carried out in collaboration with D. Angeli, and parts of it with J. Ferrell, G. Enciso, and P. de Leenheer.) |

| Date: | Tuesday, November 23, 2004, Time: 4:30 p.m., Location: Fine Hall 322 |
| Abstract: | The purpose of my talk is to introduce triangulated categories related to singularities of algebraic varieties and to establish a connection of these categories with categories of D-branes in Landau-Ginzburg models. |
| Statistical Mechanics Seminar | |
| Topic: | Linear response far from equilibrium |
| Presenter: | David Ruelle, IHES |
| Date: | Wednesday, November 24, 2004, Time: 2:00 p.m., Location: Jadwin 343 |
| Abstract: | The linear response in nonequilibrium statistical mechanics can be described mathematically as the differentiation of an Sinai-Ruelle-Bowen (SRB) measure with respect to a parameter. For certain types of dynamics (uniformly hyperbolic) one gets a very satisfactory description, with a modified fluctuation-disssipation theorem, and analyticity properties correponding to "causality". For other systems (Henon-like), "causality" seems to break down, and things are less simple. What does this mean? |

| Topic: | Frames and the Fundamental Inequality |
| Presenter: | Jelena Kovacevic, Center for BioImage Informatics, Carnegie Mellon University |
| Date: | Monday, November 29, 2004, Time: 4:00 p.m., Location: Fine Hall 214 |
| Abstract: | In recent years, we have seen an explosion of work on frames, in particular finite frames. We find finite tight frames when the lengths of the frame elements are predetermined. In particular, we derive a ``fundamental inequality" which completely characterizes those sequences which arise as the lengths of a tight frame's elements. Furthermore, using concepts from classical physics, we show that this characterization has an intuitive physical interpretation. At the end of the talk, we also examine some recent applications of frames. |

| Presenter: | Angela Gibney, University of Pennsylvania |

| Abstract: | I'll introduce a smooth projective variety T_{d,n} whose closed points correspond to stable n-pointed rooted trees of projective spaces. When d=1 this variety is isomorphic to $\overline{M}_{0,n+1}$, the fine moduli space of stable n+1 pointed cures of genus zero. I'll describe some facts about the space T_{d,n} as well as some open problems. This talk is about joint work between myself, L. Chen and D. Krashen. |

| Topic: | Reduced Scaling Methods for Quantum Electronic Structure |
| Presenter: | Emily Carter, PACM and Mechanical & Aerospace Engineering, Princeton University |
| Date: | Monday, December 6, 2004, Time: 4:00 p.m., Location: Fine Hall 214 |
| Abstract: | The problem of solving the Schroedinger equation in quantum mechanics, in order to describe the behavior of N electrons, is in principle an N! hard problem in an infinite basis. This is due to the need to describe the correlated motion of electrons. Some typical approaches to solving this 3N-dimensional PDE will be introduced, including mean-field and many-body methods. An analysis of their scaling properties will be given. My research group's particular strategies for reducing the prohibitive scaling of these methods while retaining accuracy of the solution will be presented. These schemes are based on simple physical and mathematical principles, for both molecular quantum chemistry and for condensed matter electronic structure. We will end with an outlook of the applied mathematical research challenges that remain for describing large numbers (e.g., thousands) of atoms with quantum mechanics. When these challenges are overcome, we will be able to predict the behavior of complicated molecules and materials with unprecedented fidelity. |
