Statistical Mechanics Seminar
Topic: New Results on the Hartree-Fock-Bogolubov Approximation for Many-Fermion Systems
Presenter: Volker Bach, University of Mainz
Date:  Wednesday, October 3, 2007, Time: 2:00 p.m., Location: Jadwin 343
Abstract: The lecture reviews the progress on the mathematically rigorous formulation and study of one of the most commonly used approximation methods for many-fermion systems, the Hartree-Fock approximation. In particular, the following issues will be addressed: The justification of the HF approximation in form of an error bound; The analysis of the magnetic order phase diagram for the HF approximation for the Hubbard model: Para-, Ferro-, or Antiferromagnetism; The generalization of HF theory, called Hartree-Fock-Bogolubov theory, to attractive interactions which leads to the appearance of BCS-type Cooper pairs.
   
Department Colloquium
Topic: A uniqueness property of the Kerr spacetimes
Presenter: Alexandru Ionescu, University of Wisconsin
Date:  Wednesday, October 3, 2007, Time: 4:30 p.m., Location: Fine Hall 314
Abstract: In astrophysics, "no hair" theorems postulate that all physically relevant black hole solutions of the Einstein vacuum equations can be described by two parameters: the mass of the black hole and its angular momentum. Such theorems, which go back to work of Hawking, Carter, and Robinson, are known to hold under suitable assumptions, including real analiticity. I will talk about some recent work with Sergiu Klainerman on proving a conditional "no hair" theorem in the class of smooth manifolds. Our approach is based on certain analytical tools, such as Carleman estimates and uniqueness properties of solutions of nonlinear wave equations.

Topic: Getting to Know Stacks
Presenter: Melanie Wood, Princeton University
Date:  Thursday, October 4, 2007, Time: 12:30 p.m., Location: Fine Hall 110
Abstract: A stack is a type of space that comes up naturally in several contexts, but is often hidden behind a lot of technical definitions. We'll talk about where and how you might encounter stacks, and see how to recognize "stacky" behavior. We'll see some examples of stacks that are friendly, and give advice for how to be less afraid when you meet a stack that isn't.
   
Ergodic Theory and Statistical Mechanics Seminar
Topic: Rate of convergence of geometric symmetrizations
Presenter: Bo'az Klartag, Princeton University
Date:  Thursday, October 4, 2007, Time: 2:00 p.m., Location: Fine Hall 401
Abstract: Consider Steiner symmetrizations of convex bodies, say, in three dimensions. It is well known that for any convex body K, an appropriate sequence of consecutive Steiner symmetrizations of K converges to a Euclidean ball. How fast is this convergence? For any convex body and a positive epsilon, one may apply C log2(epsilon) symmetrizations that will make it only epsilon far from a Euclidean ball. The constant C is universal. This surprisingly good dependence on epsilon stems mainly from the random nature of the symmetrization process we use.
   
Discrete Mathematics Seminar
Topic: Even pairs in Berge graphs
Presenter: Maria Chudnovsky, Columbia/CMI
Date:  Thursday, October 4, 2007, Time: 2:15 p.m., Location: Fine Hall 224
Abstract:

An even pair in a graph is a pair of non-adjacent vertices so that every induced path between them has even length. A graph is called "Berge" if no induced subgraph of it is a cycle of odd length at least five or the complement of one. In my talk I will discuss two results, obtained in joint work with Paul Seymour, about even pairs in Berge graphs.

The first result is a a simplification of the proof of the Strong Perfect Graph Theorem (which we proved a few years ago in joint work with Neil Robertson, Paul Seymour and Robin Thomas). We were able to replace the last 55 pages of the proof (which are the least intuitive part of it) with a much shorter and simpler argument. This simplification is based on an approach by Maffray and Trotignon that allowed us to find even pairs in certain classes of Berge graphs.

The second is a result about even pairs in Berge graphs with no clique of size four. At the time this abstract is being written, we have not finished checking all the details, but we believe that we can prove a theorem that describes all K_4-free Berge graph that do not have even pairs.

   
Joint Princeton University/IAS Number Theory Seminar
Topic: On the periods of automorphic forms on special orthogonal groups and the Gross-Prasad conjecture
Presenter: Atsushi Ichino, Institute for Advanced Study
Date:  Thursday, October 4, 2007, Time: 4:30 p.m., Location: IAS SH-101
Abstract: A period of an automorphic form on a reductive group G over a number field is defined by its integral over a subgroup H of G. Such periods are often related to special values of automorphic L-functions. In this talk, we present a conjecture in the case of special orthogonal groups, which can be regarded as a refinement of the global Gross-Prasad conjecture about the restriction of automorphic representations of SO(n+1) to SO(n). If time permits, we also discuss a relation of our conjecture to Arthur's conjecture on the multiplicity of representations in the space of automorphic forms. This is a joint work with Tamotsu Ikeda.
   
Topology Seminar
Topic: Piecewise Polynomials and the Equivariant Cohomology of Weighted Projective Spaces
Presenter: Tony Bahri, Rider University
Date:  Thursday, October 4, 2007, Time: 4:30 p.m., Location: Fine Hall 314
Abstract: A report of joint work with Matthias Franz and Nigel Ray.
As toric varieties, weighted projective spaces have a natural torus action. We describe the integral equivariant cohomology ring, with respect to this action, in terms of piecewise polynomial functions on the underlying fan. Unlike the ordinary integral cohomology, this ring distinguishes among weighted projective spaces.
   
Differential Geometry and Geometric Analysis Seminar
Topic: Regularity results for nonlocal elliptic equations
Presenter: Luis Silvestre, Courant Institute, NY
Date:  Friday, October 5, 2007, Time: 3:00 p.m., Location: Fine Hall 314
Abstract: We study nonlinear integro-differential equations. Typical examples are the ones that arise from control problems with discontinuous Levy processes. We can think of these as nonlinear equations of fractional order. Our aim is to extend the theory of fully nonlinear elliptic equations to this class of equations. We are able to obtain a result analogous to the Alexandroff estimate, Harnack inequality and $C^{1,\alpha}$ estimates. As the order of the equation approaches two, in the limit our estimates become the classical estimates for second order elliptic pdes.
   
PACM Colloquium
Topic: Modeling complex brain dynamics
Presenter: Carlos Brody, Molecular Biology, Princeton University
Date:  Monday, October 8, 2007, Time: 4:00 p.m., Location: Fine Hall 214
Abstract: It is thought that the neural activity in specific, specialized structures of the brain is responsible for what we experience as "cognition." I will describe recordings from the brains of awake primates, performing a cognitive task, that show that the relevant neural activity has a very complex and heterogeneous dynamical pattern. In these recordings, only a few neurons (less than 10) are recorded from at a time, and only a few hundreds of neurons are recorded from in the course of an entire experiment. Yet the number of neurons in the relevant brain areas is in the tens of millions. We aim to build dynamical systems models that describe the mechanisms responsible for the observed patterns in the data. How can we build models that are faithful to the complexity of the data, and faithful to the very large number of neurons involved, yet simple enough that we can understand their principles of operation?

Topic: Two Theoretical Problems in Biophysics
Presenter: William Bialek, Princeton University
Date:  Wednesday, October 10, 2007, Time: 2:00 p.m., Location: Jadwin 343
Abstract: The phenomena of life are beautiful, but it has been difficult to tame these phenomena to the point where we have productive (not to mention elegant) theories, as in the rest of physics. This talk will describe two efforts in this direction, both very much works in progress. In the first problem we take our cue from experiment, and try to find a path from the measured correlations among pairs of neurons to the global, collective properties of an entire neural network. Maximum entropy methods turn out to be surprisingly successful, and following this path we find connections from real data to various ideas from statistical physics, including the possibility that real networks of neurons are poised at a critical point. In the second problem, we consider the possibility that some biological mechanisms have been selected to optimize the transmission of information in the presence of various physical constraints. This idea is attractive because it can unify our understanding of signaling in many different systems, from genes to neurons. I'll give a quick review of how these ideas have been used in the context of neural coding, then turn to new work on the very first events where genes are turned on and off during the development of a fruit fly embryo, where the theory is in remarkably good agreement with recent experiments.
   
Department Colloquium
Topic: Perverse coherent sheaves on a blowup surface
Presenter: Hiraku Nakajima, Kyoto and IAS
Date:  Wednesday, October 10, 2007, Time: 4:30 p.m., Location: Fine Hall 314
Abstract: The blowup of a complex surface at a point is one of the most basic birational operation in algebraic geometry. It replaces a point by a projective line. In topology, it corresponds to making the connected sum with the projective plane with the opposite orientation. The relation between moduli spaces of coherent sheaves (vector bundles with singularities) on the original surface and on the blowup surface is of our interest. In this talk, I will explain that two moduli spaces can be understood via the `wall-crossing', i.e., a change of the stability parameters. Hence two moduli spaces are connected by a sequence of birational operations. (Joint work with Kota Yoshioka)
   
Ergodic Theory and Statistical Mechanics Seminar
Topic: Random walks on Young diagrams and limit transitions
Presenter: Grigori Olshanski, Dobrushin Lab, Moscow, and U. Penn
Date:  Thursday, October 11, 2007, Time: 2:00 p.m., Location: Fine Hall 401
Abstract: I will talk about a family of stationary Markov processes taking values in an infinite-dimensional state space. This space can be interpreted as a space of infinite configurations of particles on the line. The processes arise via a scaling limit transition from Markov chains on the set of Young diagrams. The stationary distributions have a representation-theoretic meaning. A similarity with models from random matrix theory will be discussed.

Topic: Counting points on Igusa varieties and stabilization
Presenter: S.W.Shin, IAS
Date:  Thursday, October 11, 2007, Time: 4:15 p.m., Location: SH-101
Abstract: In the beginning we review the classical method of computing the cohomology of PEL-type Shimura varieties with good reduction modulo p, and explain the tools that are useful for studying the bad reduction of compact Shimura varieties. Then we introduce the counting point formula for Igusa varieties, which plays the role of the analogous formula for the mod p fiber of Shimura varieties with good reduction. Time permitting, we will discuss how our formula can be stabilized.

Topology Seminar
Topic: Spherically-fibered coisotropic submanifolds
Presenter: Tim Perutz, Columbia University
Date:  Thursday, October 11, 2007, Time: 4:30 p.m., Location: Fine Hall 314
Abstract: The title refers to a class of submanifolds of symplectic manifolds which arise in connection with "complex Morse-Bott" functions. I'll talk about ongoing work concerning two general exact triangles in symplectic Floer homology, both associated with such submanifolds: a "Gysin" sequence and a "fibered Dehn twist" sequence. Motivating examples come from a symplectic model for Seiberg-Witten Floer theory, in which these triangles appear as counterparts of a connected sum formula and of the surgery triangle, respectively.

Topic: Symplectic Floer homology, Nielsen-Thurston theory and generalised Arnold conjecture
Presenter: Alexander Felshtyn, Boise State University
Date:  Friday, October 12, 2007, Time: 1:30 p.m., Location: Fine Hall 314
Abstract: We describe the connection between symplectic Floer homology of symplectomorphisms of surface and Nielsen-Thurston theory. Symplectic zeta functions and asymptotic invariant of symplectic origin are defined. For general symplectomorphism of surface we propose a generalisation of Arnold conjecture for hamiltonian symplectomorphisms.

Topic: Shear-induced Mixing
Presenter: Lai-Sang Young, Courant Institute, New York University
Date:  Monday, October 22, 2007, Time: 4:00 p.m., Location: Fine Hall 214
Abstract: I will discuss the phenomenon of shear-induced mixing in driven dynamical systems. The unforced system is assumed to have certain simple underlying structures, such as attracting periodic solutions or equilibria undergoing Hopf bifurcations. Specifics of the defining equations are unimportant. A geometric mechanism for producing chaos - or equivalently promoting mixing - is proposed. In the case of periodic kicks followed by long periods of relaxation, rigorous results establishing the presence of strange attractors with SRB measures are presented. These attractors belong in a class of chaotic systems that can be modeled (roughly) by countable-state Markov chains. From this I deduce information on their statistical properties. In the last part of this talk, I will explore numerically the range of validity of the geometric ideas discussed. Examples including stochastically forced coupled oscillators will be presented.

PACM Colloquium
Topic: Functional Sparsity
Presenter: John Lafferty, Computer Science, Carnegie Mellon University
Date:  Monday, November 5, 2007, Time: 4:00 p.m., Location: Fine Hall 214
Abstract: Substantial progress has recently been made on understanding the behavior of sparse linear models in the high dimensional setting, where the number the variables can greatly exceed the number of samples. This problem has attracted the interest of multiple communities, including applied mathematics, signal processing, statistics, and machine learning. But linear models often rely on unrealistically strong assumptions, made more by convenience than conviction. Can we understand the properties of high dimensional nonlinear functions that enable them to be estimated accurately from sparse data? In this talk we present some progress on this problem, showing that many of the recent results for sparse linear models can be extended to the infinite dimensional setting of nonparametric function estimation. In particular, we present some theory for estimating sparse additive models, together with algorithms that are scalable to high dimensions. We illustrate these ideas with an application to functional sparse coding of natural images. This is joint work with Han Liu, Pradeep Ravikumar, and Larry Wasserman.

Topic: A Sharp Compactness Theorem for Genus-One Pseudo-Holomorphic Maps and Applications
Presenter: Aleksey Zinger, Stony-Brook University
Date:  Friday, December 7, 2007, Time: 1:30 p.m., Location: Fine Hall 314
Abstract: Moduli spaces of stable maps are often called ``compactifications" of spaces of maps from smooth domains. In general, however, the latter are not dense in former. For the model target space P^n, the moduli space of genus 0 maps is an honest compactification, but positive genus moduli spaces have components of different dimensions. This seemingly technical point leads to very different and generally poorly understood behavior of positive-genus Gromov-Witten invariants. In this talk I will describe a sharp version of Gromov's compactness theorem for genus-one pseudo-holomorphic maps that leads to much smaller ``compactifications" of spaces of maps from smooth domains. These are sharp in my cases, as well as with respect to being naturally. Applications of this compactness theorem include new genus 1 GW-invariants with geometric properties similar to those of genus 0 GW -invariants, better understanding of the standard genus 1 GW-invariants, a natural smooth compactification of the Hilbert scheme of smooth genus 1 curves in P^n, and the proof of the 1993 BCOV mirror symmetry prediction for genus 1 GW-invariants of a quintic threefold.
   
PACM Colloquium
Topic: Collective motion and decision-making in animal groups
Presenter: Iain Couzin, Ecology & Evolutionary Biology, Princeton University
Date:  Monday, December 10, 2007, Time: 4:00 p.m., Location: Fine Hall 214
Abstract:

Animal groups such as bird flocks, insect swarms and fish schools are spectacular, ecologically important and sometimes devastating features of the biology of various species. Outbreaks of the desert locust, for example, can invade approximately one fifth of the Earth's land surface and are estimated to affect the livelihood of one in ten people on the planet. Using a combined theoretical and experimental approach involving insect and vertebrate groups I will address how, and why, individuals move in unison and investigate the principals of information transfer in these groups, particularly focusing on leadership and collective consensus decision-making.

For very large animal groups, despite huge differences in the size and cognitive abilities of group members, recent models from theoretical physics ('self-propelled particle', SPP, models) have suggested that general principles underlie collective motion. Such models demonstrate that some group-level properties may be largely independent of the types of animals involved. I shall present recent experimental work on locusts that validates some of the predictions of simple mechanistic models including a density-dependent "phase transition" from disordered to ordered motion.

Details of the mechanism by which individuals interact, however, also provide important biological insights into swarm behaviour. Using laboratory studies involving nerve manipulation and field experiments we demonstrate that some swarming insects are in effect on a "forced march" driven by cannibalism.

These results will be discussed in the context of the evolution of functional complexity and pattern formation in biological systems.
