Dilute quantum gases |
Presenter: |
Robert Seiringer, Princeton University |
Date: |
Wednesday, October 18, 2006, Time: 4:30 p.m., Location: Fine 314 |
Abstract: |
We present an overview of mathematical results on the low temperature properties of dilute quantum gases, which have been obtained in the past few years. The discussion includes, for instance, results on the free energy in the thermodynamic limit, and on Bose-Einstein condensation, Superfluidity and quantized vortices in trapped gases. All these properties are intensely being studied in current experiments on cold atomic gases. We will give a brief description of the mathematics involved in understanding these phenomena, starting from the underlying many-body Schroedinger equation. |

Two optimization problems arising from polling and nonhomogeneous poisson processes |
Presenter: |
Jonathan Eckstein, Rutgers University |
Date: |
Wednesday, October 18, 2006, Time: 4:30 p.m., Location: E-219, E-Quad |
Abstract: |
This talk presents two optimization problems arising from the same applied probability application, in which we monitor an information source to which data are added at times modeled by a nonhomogeneous Poisson process. In the first application, we suppose that the arrival rate function is known and we may poll the information source a limited number of times over some planning horizon. We develop an objective function for evaluating the quality of a polling schedule, and approximately optimize it by a combination of dynamic programming and local search. The dynamic programming algorithm uses a discrete time approximation for which we are able to prove quality guarantees. The second application addresses the more fundamental problem of estimating the arrival rate function of a nonhomogeneous Poisson process. We argue that nonnegative splines constitute an attractive class of functions over which to search, and show that maximum likelihood estimation over this class reduces to convex optimization over semidefinite cone and linear constraints. In particular, estimation by cubic splines reduces to convex nonlinear programming. We present numerical results in which we use a cross-validation procedure to set the number of spline knots. Our general approach can easily be adapted to density estimation and other related problems. Various portions of this work joint with: Farid Alizadeh, Avigdor Gal, Nilay Noyan, Gabor Rudolf. |

Distributional properties of cocycles and stationary random walks |
Presenter: |
Klaus Schmidt, Schroedinger Institute |
Date: |
Thursday, October 19, 2006, Time: 2:00 p.m., Location: Fine 401 |
Abstract: |
If $(X_n)$ is an ergodic stationary stochastic process and $Y_n=X_0+\dots + X_{n-1}$ the associated random walk, what can be said about recurrence of $(Y_n)$ if one only knows the distributions of the $Y_n,n\ge1$? This question immediately translates in to a question about Birkhoff sums for ergodic transformations, and by using methods from ergodic theory (orbit equivalence) one can prove for $d=2$, for example, that $(Y_n)$ is recurrent whenever it satisfies a very weak form of the central limit theorem. Another result about distributional properties of cocycles is the following: let $T$ be a measure-preserving and ergodic transformation of a probability space $(X,\mu )$, $f$ a positive real valued Borel map with $\int f\,d\mu =1$, and let $T^f$ be the flow under the function $f$ with base $T$. If $T$ is mixing and $T^f$ is weakly mixing, or if $T$ is ergodic and $T^f$ is mixing, then the Birkhoff sums $f(n,.),\,n\ge0$, of $f$ 'disperse'. |

Conservation laws for conformally invariant Lagrangian and Schroedinger systems |
Presenter: |
Tristan Riviere, ETHZ, Zurich |
Date: |
Friday, October 20, 2006, Time: 3:00 p.m., Location: Fine 314 |
Abstract: |
We will explain how to write 2-dimensional conformally invariant non-linear elliptic PDE (harmonic map equation, prescribed mean curvature equations...etc) in divergence form. These divergence-free quantities generalize to target manifolds without symmetries the well known conservation laws for weakly harmonic maps into homogeneous spaces. From this form we can recover, without the use of moving frame, all the classical regularity results known for 2-dimensional conformally invariant non-linear elliptic PDE . It enables us also to establish new results. In particular we solve a conjecture by E. Heinz asserting that the solutions to the prescribed bounded mean curvature equation in arbitrary manifolds are continuous. Our approach permits also to prove a more general conjecture by S.Hildebrandt claiming that critical points of continuously differentiable second order elliptic conformally invariant Lagrangian in two dimensions are continuous. We will explain how these results are deduced from a more general one on solutions to Schroedinger systems with antisymetric potentials. |

Solving Nasty Optimization Problems in Science and Engineering |
Presenter: |
Margaret Wright, Computer Science Department, CIMS, New York University |
Date: |
Monday, October 23, 2006, Time: 4:00 p.m., Location: Fine 214 |
Abstract: |
Many important optimization problems in science and engineering involve functions that can fairly be described as "nasty", which can mean any or all of wildly nonlinear, nonsmooth, noisy, and defined through complex black-box simulation or error-prone experimental data. Because it is often impossible or impractical to calculate derivatives of these functions, non-derivative methods are the only feasible choice. These methods are in the midst of a renaissance involving research on their theoretical and computational properties, as well as investigation of which methods are best suited for which applications. This talk will include examples of challenging problems along with the speaker's assessment of the state of the art in non-derivative optimization methods.

An elementary derivation of Thomae's Formula and some generalizations |

Hershel Farkas, Hebrew University of Jerusalem; SUNY Stony Brook |
Date: |
Tuesday, October 24, 2006, Time: 4:30 p.m., Location: Fine 322 |
Abstract: |
In this talk I shall review the relevant facts concerning hyperelliptic Riemann surfaces and then show how the formulae of Thomae which connect the algebraic and transcendental parameters of a hyperelliptic surface can be derived as an almost immediate consequence of the definitions and elementary properties. More precisely, Thomae's formulae are polynomial equations relating theta constants and the branchpoints of the double cover of P^1 by the hyperelliptic curve. Time permitting, I shall say something about generalizations to other families of curves. |

Correlation Estimates for Quantum Many-Body Systems at Positive Temperature |
Presenter: |
Robert Seiringer, Princeton University |
Date: |
Tuesday, October 24, 2006, Time: 4:30 p.m., Location: Jadwin 343 |
Abstract: |
We present a method for obtaining bounds on the expectation value of certain two-body interaction potentials in a general state on Fock space in terms of the corresponding expectation value for thermal equilibrium states of non-interacting systems. The difference can be dominated by the difference in the free energies. This method can be viewed as a rigorous form of first order perturbation theory for many-body systems at positive temperature. One of the key ingredients is the strong subadditivity of the von-Neumann entropy. As an application, we give a proof of the first two terms in a high density (and high temperature) expansion of the free energy of jellium with Coulomb interactions, both in the fermionic and bosonic case. For bosons, our method works above the non-interacting gas transition temperature for Bose-Einstein condensation. |

A fictitious play approach to complex systems optimization |
Presenter: |
Robert Smith, University of Michigan |
Date: |
Tuesday, October 24, 2006, Time: 4:30 p.m., Location: E-219, E-Quad |
Abstract: |
Complex systems consisting of a large number of interacting components are in practice increasingly modeled through computer simulations rather than via traditional equation based approaches. The resulting model typically allows for little or no structural assumptions on the form of the objective function or constraints, thus posing a challenging optimization problem. We explore in this talk a novel optimization paradigm inherited from game theory that animates the components of the system within a non-cooperative game of identical interest. The optimizations take place though individual best replies of the players, thus vastly reducing the dimensionality of the optimization problems solved (the components’ joint interactions are reflected indirectly through their shared objective function). We will illustrate the approach by discussing an application to a joint production systems optimization project within the GM Collaborative Research Laboratory at the University of Michigan. |

Quasi-isometric classification of graph manifolds |
Presenter: |
Jason Behrstock, University of Utah |
Date: |
Thursday, October 26, 2006, Time: 4:30 p.m., Location: Fine 314 |
Abstract: |
We show that the fundamental groups of any two closed irreducible non-geometric graph manifolds are quasi-isometric, resolving a question of Kapovich and Leeb. We also classify the quasi-isometry types of fundamental groups of graph manifolds with boundary in terms of certain finite two-colored graphs. This shows, for instance, that there are exactly 204,535,126 quasi-isometry types of graph manifolds having 8 or fewer Seifert components. Another corollary is a quasi-isometric classification of some families of Artin groups. |

Scattering theory in models of non-relativistic QED |
Presenter: |
Benjamin Schlein, UC Davis |
Date: |
Monday, October 30, 2006, Time: 4:00 p.m., Location: Fine 110 |
Abstract: |
In this talk I will review some recent results concerning the scattering theory in systems of non-relativistic matter coupled to a quantized radiation field. In particular I will consider models describing the physical processes of Rayleigh and Compton scattering. Rayleigh scattering refers to the scattering of photons (the field quanta of the electromagnetic field) at atoms with total energy below the ionization threshold. Compton scattering, on the other hand, denotes the scattering of photons at free electrons. I plan to explain some of the mathematical methods used in the study of these models, to present some of the rigorous results which can be obtained with these methods, and to discuss some important open problems. |

Information Theory and Probability Estimation: From Shannon to Shakespeare via Laplace, Good, Turing, Hardy, Ramanujan, and Fisher |
Presenter: |
Alon Orlitsky, ECE and CSE, University of California, San Diego |
Date: |
Monday, November 6, 2006, Time: 4:00 p.m., Location: Fine 214 |
Abstract: |
Standard information-theoretic results show that data over small, typically binary, alphabets can be compressed to Shannon's entropy limit. Yet most practical sources, such as text, audio, or video, have essentially infinite support. Compressing such sources requires estimating probabilities of unlikely, even unseen, events, a problem considered by Laplace. Of existing estimators, an ingenious if cryptic one derived by Good and Turing while deciphering the Enigma code works best yet not optimally. Hardy and Ramanujan's celebrated results on the number of integer partitions yield an asymptotically optimal estimator that compresses arbitrary-alphabet data patterns to their entropy. The same approach generalizes Fisher's seminal work estimating the number of butterfly species and its extension authenticating a poem purportedly written by The Bard. The talk covers these topics and is self contained.

Irrational triangular billiards |
Presenter: |
Richard Schwartz, Brown University |
Date: |
Wednesday, November 8, 2006, Time: 4:30 p.m., Location: Fine 314 |
Abstract: |
It is an old and open problem whether or not every triangular shaped billiard table has a periodic billiard path. The answer is known to be yes for acute, right, and rational triangles but unknown in the obtuse irrational case. Over several years, Pat Hooper and I have developed a graphical user interface, called McBilliards, with a view towards resolving the triangular billiards problem. The huge experimental output from the progran illustrates the extreme and previously unexpected complexities of the problem. In my talk I will survey the experimental evidence from McBilliards and also explain some of our rigorous results which were inspired by the experiments. |

The distribution of visible lattice points and collision times in the periodic Lorentz gas |
Presenter: |
J.Marklof, Bristol |
Date: |
Thursday, November 9, 2006, Time: 2:00 p.m., Location: Fine 401 |
Abstract: |
I will discuss two closely related problems.
(1) Take integer lattice points in a large ball of radius R and project them onto the unit sphere S centered at x. It is well known that the sequence of projected points becomes uniformly distributed on S as R becomes large. I will show that, for every fixed x, the statistical correlation functions of this sequence have limiting distributions with some remarkable properties. The proof uses Ratner's classification of ergodic measures invariant under unipotent flows.
(2) The periodic Lorentz gas describes a point particle moving in a periodic array of spherical scatterers of radius r. I'll explain why the probability for a particle to hit the first scatterer after a fixed time T has a limiting distribution in the small scatterer limt r->0 and discuss some of its properties. This particular question was raised by Sinai in the early 1980s.
This is joint work with A. Strombergsson. |

Multiple Dirichlet series attached to Weyl groups |
Presenter: |
Solomon Friedberg, Boston College |
Date: |
Thursday, November 9, 2006, Time: 4:30 p.m., Location: Fine Hall 214 |
Abstract: |
Weyl group multiple Dirichlet series are multiple Dirichlet series in several variables whose coefficients involve Gauss sums and also reflect the combinatorics of a given root system. The earliest examples came from Mellin transforms of metaplectic Eisenstein series and have been intensively studied over the last 20 years. These functions and their residues unify and generalize a number of examples which have been previously treated individually, often with applications to analytic number theory. In this lecture I give an account of some of the major research to date and the opportunities for the future. |

Abstract: |
We prove that the quintic (critical) defocussing wave equation with Dirichlet boundary conditions in a 3-d bounded domain is globally well posed in energy space. The main ingredient of the proof is an (optimal) Strichartz inequality derived from some recent spectral projector estimates by Smith and Sogge and a precise study of the boundary value problem.

Denoising Color Images |
Presenter: |
Yang Wang, Mathematics, Georgia Institute of Technology |
Date: |
Monday, November 13, 2006, Time: 4:00 p.m., Location: Fine 214 |
Abstract: |
Natural color images captured by digital cameras often exhibit noticeable noise, particularly when the pictures are taken under low lighting or artificial lighting conditions. Traditional denoising techniques, which are often tested for removing artificial noise in monochromatic images, often do not work well for noisy color images.
In this talk, we present an overview of some of the traditional methods for denoising. We discuss a new strategy, which we call the cross-channel principle, that can be applied for very effective denoising of color images. In particular we show how this principle can be applied to the total variation denoising scheme and an ENO type denoising scheme.

It is not known whether these varieties have any nontrivial vector bundles at all. |

In this talk, I will explain how to compute the trace of a power of the Frobenius endomorphism on the intersection cohomology of the Baily-Borel compactification of a Siegel modular variety. The main tools are : - Kottwitz's calculation of the number of points of PEL Shimura varieties over finite fields; - a theorem of Pink about the direct image in the Baily-Borel compactification of a local system on a Shimura variety; - a new construction of the intermediate extension of a pure perverse sheaf as a weight truncation of the full direct image. |

A new proof of the convergence of the N-particle Schroedinger dynamics for bosons towards the dynamics generated by the Hartree equation in the mean-field limit. For a restricted class of two-body interactions, we obtain convergence estimates uniform in h- bar, up to an exponentially small remainder. For h-bar = 0, the classical dynamics in the mean-field limit is given by the Vlasov equation. (Joint work with J.Froehlich and S.Schwarz.) |

Selective excitation is an essential ingredient of any application of nuclear magnetic resonance, e.g. MR-imaging or spectroscopy. I will explain how the problem of selective excitation of 2-level quantum systems leads directly to the classical inverse scattering problem for the 2x2 AKNS system. We discuss the analysis of the inverse scattering transform and the role of non-linearity. I then show how a viable numerical algorithm, based on the hard pulse approximation, allows for the practical and accurate solution of this problem. |
