Week of October 9 - October 11, 2002

 

Statistical Mechanics Seminar

Topic:       Introduction to some new ideas in non-equilibrium statistical mechanics

Presenter: David Ruelle, IHES, France

Date:         Wednesday, October 9, 2002, Time: 2:00 p.m., Location: Jadwin 343

Abstract:    Nonequilibrium statistical mechanics has recently been idealized as the study of a certain differentiable dynamical system.  This raises a number of physical and mathematical questions which will be discussed. In particular we shall study the response of a system to a change of forces acting on it.

  

Department Colloquium

Topic:       Nonlinear PDE's in Conformal Geometry

Presenter:  Alice (Sun-Yung) ChangPrinceton University

Date:         Wednesday, October 9, 2002, Time: 4:30 p.m., Location: Fine Hall 314

Abstract:   Second order elliptic equations have always been an important tool in the study of problems in geometry.  In this talk, I will describe some recent efforts to extend the role played by second order elliptic operators to some higher order ones; some natural curvature functions related to these operators and some geometric implications.

   On manifolds of dimension four, one example of a conformally covariant operator is the fourth order operator discovered by Paneitz in 1983 with its leading symbol the bi-Laplace operator.  The Paneitz operator applied to a conformal factor determines a fourth order curvature invariant which we will call the Q-curvature.  The Q-curvature equation is intimately related to a fully non-linear second order elliptic equation, which prescribes part of the inegrand of the Gauss-Bonnett formula.
   As an application, I will report a "sphere theorem" for four-manifolds )word of S.-Y.A. Chang, M. Gursky, and P. Yang).  In contrast to classical sphere theorems, , which typically impose pointewise pinching conditions on the sectional curvature, this resuult only assumes L2-bounds for certain components of the curvature tensor, along with a sign on the Yamabe invariant.

Topology Seminar

Topic:        Surface singularities with homology 3-sphere links

Presenter:  Walter Neumann,  Columbia University and Barnard

Date:          Thursday, October 10, 2002,  Time:  4:00 p.m., Location:  Fine Hall 314

Abstract:    The Casson Invariant Conjecture says that the signature of  the Milnor fiber of a complete intersection singularity with homology sphere link should be eight times the Casson invariant of the link. It suggests that the Milnor fiber is a topologically natural coboundary for the link.  Recent progress includes a conjectural classification of the 3-manifolds, singularities, and Milnor fibers to which this applies, and a proof of the conjecture for a largish subclass of these.

 

Joint Princeton University/IAS Number Theory Seminar *** Please note change in time and location

Topic:        Congrueneces involving non tempered automorphic forms and Bloch-Kato conjectures

Presenter:  Joel Bellaiche,  IAS

Date:          Thursday, October 10, 2002,  Time:  4:00 p.m., Location:  SH-101 at IAS

Abstract:    In this talk, I will present a proof of some case of Bloch-Kato conjecture for Hecke characters of quadratic imaginary fields, which is based on a new method involving congruences between non-tempered automorphic forms and tempered one for  unitary groups in three variables.  We will also explain how this method coul'd be generalized, assuming the Arthur conjectures on multiplicty formulae for the non-tempered spectrum, to some other reductive groups, to give proof of other case of Bloch-Kato conjecture.

 

Noetherian Ring Seminar

Topic:        Total positivity and flag varieties

Presenter:  Konstanze Rietsch,  King's College, London

Date:          Thursday, October 10, 2002,  Time:  2:00 p.m., Location:  Fine Hall 314

Abstract:    A matrix is called totally positive if all of its minors are positive. This concept was generalized by Lusztig to arbitrary type and related with canonical bases. This talk will be an introduction and survey to the topic of total positivity especially in the context of flag varieties.

Presenter:  Ken Baker,  University of Texas at Austin

Date:          Friday, October 11, 2002,  Time:  12:30 p.m., Location:  Fine Hall 801

Abstract:    John Berge gave a conjecturally complete list of knots with lens space surgeries. In this talk I will exhibit a subset of these knots which have arbitrarily large hyperbolic volume and discuss a consequence of this result.

Geometric Analysis  Seminar

Presenter:  Chris BishopSUNY at Stony Brook

Date:          Friday, October 11, 2002, Time: 3:00 p.m., Location: Fine Hall 314

 

Week of October 14 - October 18, 2002

 

Analysis Seminar

Topic:       Dyadic models for the equations of fluid motion, and an example of turning models into reality

Presenter:  Natasa PavlovicPrinceton University

Date:          Monday, October 14, 2002, Time: 4:00 p.m., Location: Fine Hall 314

Abstract:    This talk will be about dyadic models for the equations of fluid motion. In the talk we shall introduce a dyadic model for the Euler and the Navier-Stokes equations with hyper-dissipation. For the dyadic Euler equations we prove finite time blow-up. In the context of the dyadic Navier-Stokes equations with hyper-dissipation we prove finite time blow-up in case when the degree of dissipation is sufficiently small.  Also we shall discuss a partial regularity result for the dyadic Navier-Stokes equations with hyper-dissipation, which could be turned into a result for the actual Navier-Stokes equations with  hyper-dissipation. This talk is based on joint work with Susan Friedlander and Nets Katz.

 

PACM Colloquium

Topic:       Theoretical and Numerical Analysis for Some Non-linear Interface Problems

Presenter: Zhilin Li, North Carolina State University

Date:           Monday, October 14, 2002, Time: 4:00 p.m., Location: Fine Hall 214

Abstract:    Non-linear partial differential equations with discontinuity in the coefficient have many applications. In this talk, I will focus on two different non-linear interface problems. One is the potential equation for magneto-rhological (MR) fluid that contains metal particles. The permeability is discontinuous across the interface between the fluid and the particles. The second problem is the weighted minimal surface problem. We have generalized the Sneil's law for optical path to the three dimensional weighted minimal surface problem. Numerically, we use the substitution method to solve the non-linear PDE. Since the coefficient of the potential  equation depends on the gradient of the solution, we use the maximum preserving immersed interface method coupled with multigrid solvers to solve the linearized problems. Numerical examples will also be presented.

 

Algebraic Geometry Seminar

Topic:        Rational varieties over finite fields 

Presenter:  János KollárPrinceton University

Date:          Tuesday, October 15, 2002, Time: 4:30 p.m., Location: Fine Hall 322

 

Statistical Mechanics Seminar

Topic:      Random graphs with a positive density of triangles

Presenter: J.P. Eckmann, University of Geneva

Date:         Wednesday, October 16, 2002, Time: 2:00 p.m., Location: Jadwin 343

Abstract:   In a study with E. Moses (Weizmann) we discovered that the graph of the World Wide Web and many other graphs occurring in the Sciences have a density of triangles which is much higher than what can be expected for a random graph. As a consequence, P. Collet and I studied the "statistical mechanics" of subsets of random graphs with a positive density of triangles. This corresponds to a theory of extremely large deviations. If time permits, I will also describe a few aspects of the work on the WWW.

Topology Seminar

Topic:        Simple closed geodesics on surfaces.

Presenter:   Nancy Hingston, the College of New Jersey

Date:          Thursday, October 17, 2002:  Time:  4:00, Location:  Fine Hall 314

 

Joint Princeton University/IAS Number Theory Seminar

Topic:        Epsilon Constants and Orthogonal Representations

Presenter:  Darren Glass,  Columbia University

Date:          Thursday, October 17, 2002:  Time:  4:30, Location:  Fine Hall 322

Abstract:    Suppose X is an arithmetic surface and G is a finite group which acts tamely on X. We define Y to be the quotient scheme Y and we let V be a representation of G. Associated to this information, we can define an L-function L(Y,V,s) which satisfies a certain functional equation involving an epsilon constant. Calculating these epsilon constants is very difficult in general, but under additional hypotheses the situation can greatly simplify. My research assumes that V is an orthogonal representation, and in that case reduces the calculation to a calculation about how the representation acts at only a finite number of points.

PACM Colloquium

Topic:        Theory and Computation of Resonances of Photonic Microstuctures

Presenter:   Michael Weinstein, Bell Laboratories

Date:           Monday, October 21, 2002, Time: 4:00 p.m., Location: Fine Hall 214

Abstract:    Photonic crystal waveguides are a class of optical waveguides with novel transverse microstructure. A great deal of tunability of optical properties is achieved through variations in the geometry of microfeatures, their distribution and refractive index contrasts. We discuss a multiple scale approach to the study of photonic crystal waveguides. Energy escapes from the core due to a combination of propagation and tunneling. Of central importance are leaky modes (resonance states) and their associated complex effective indices (scattering resonance poles). The leading order theory agrees with classical homogenization theory, describing an effective homogeneous medium with dielectric properties given by an appropriate averaging of the refractive index profile. We compute the first non-trivial correction, which takes into account the microstructure, and find that the higher order homogenization expansion gives very good agreement with full simulations by Fourier and multipole methods. The higher order expansion is crucial for estimation of leakage rates; in various examples of physical interest, the leading order (homogenization) gives a substantial underestimation. Finally, a rigorous justification of the homogenization expansion of scattering resonances is obtained as part of a resonance perturbation theory for an appropriate "preconditioned" Lippmann-Schwinger equation.

 

 Arnold's Diffusion Seminar

Statistical Mechanics Seminar

Topic:       Magnets, microchips, memories and markets; statistical physics of complex systems

Presenter:  David Sherrington, Oxford University and IAS

Date:         Wednesday, October 23, 2002, Time: 2:00 p.m., Location: Jadwin 343

Abstract:    Disorder and frustration in the interactions between even quite simple microscopic entities can lead to complex macroscopic co-operative behaviour, whose understanding has required the development of novel concepts and techniques and continues to pose challenges. In this talk an overview will be given of the origin and character of such complexity and its conceptual understanding. It will be shown how resultant concepts can be fruitfully and symbiotically transferred between systems of physically quite different appearance. Illustrations will include frustrated magnets, (spin glasses), hard optimization problems (microchip design), associative memories (as in the brain or artificial neural networks) and simple markets (inspired by economics).

 

Department Colloquium

Topic:     Algebraic Geometry of Nash Equilibria

Presenter:  Bernd SturmfelsUC at Berkeley

Date:          Wednesday, October 23, 2002, Time: 4:30 p.m., Location: Fine Hall 314

Abstract:    We present an algebraic approach to Nash equilibria in game theory, along the lines of Chapter 6 in my new book "Solving Systems of  Polynomial Equations" (http://math.berkeley.edu/~bernd/cbms.html). The set of all Nash equilibria of an N-person game is a real algebraic variety, which is typically a finite set. A combinatorial formula for its expected cardinality was given by the economists McKelvey and McLennan in 1997. We show how to find all Nash equilibria using computational algebraic geometry, and we present the Universality Theorem (proved by Ruchira Datta in 2002) which states that every real algebraic variety arises from a game with three players.

Special Colloquium

Topic:        Primes is in P

Presenter:   Manindra Agrawal, Kanpur, India

Date:          Monday, October 28, 2002:  Time:  11:00 a.m., Location:  A01 McDonnell Hall

Abstract:    Determining if a given number is prime has engaged the attention of theoretical computer scientists for several decades.  Several efforts have been made to design an efficient (in other words, polynomial-time) algorithm.  These include Miller’s test (a polynomial-time algorithm; however, it is correct only assuming Extended Riemann Hypothesis), Rabin’s and Solovey-Strassen’s tests (randomized polynomial-time tests), Adelman-Pomerance-Rumeli’s test (deterministic test requiring slightly super-polynomial time), etc.  It has remained a major open problem to design an unconditional deterministic polynomial-time algorithm for the problem. In this talk, we present the first such algorithm.

Analysis Seminar

Topic:      Purely Nonlinear Instability of Minimal Energy Standing Waves

Presenter:  Andrew ComechUniversity of North Carolina

Date:          Monday, November 4, 2002, Time: 4:00 p.m., Location: Fine Hall 314

Abstract:    For a variety of nonlinearities, the nonlinear Schroedinger equation is known to possess localized quasistationary solutions ("standing waves"). We prove that in the generic situation the standing wave of minimal energy among all other standing waves is unstable. This case was falling out of the scope of the classical paper by Grillakis, Shatah, and Strauss on orbital stability of standing waves. An interesting feature of the problem is the absence of (exponential) instability in the linearized system; in this sense, the resulting instability is ``purely nonlinear''. Essentially, the instability is caused by higher algebraic degeneracy of zero eigenvalue in the spectrum of the linearized system. The result can be generalized to abstract Hamiltonian systems with U(1) symmetry.

 

PACM Colloquium

Topic:        The Forced van der Pol Equation: New Insights on an Old Problem

Presenter:   John Guckenheimer, Cornell University

Date:           Monday, November 4, 2002, Time: 4:00 p.m., Location: Fine Hall 214

Abstract:    The forced van der Pol equation is the original example of chaos in dynamical systems. It is also an example of relaxation oscillations, periodic motions with short and fast time scales. This lecture describes joint work, primarily with Kathleen Hoffman and Warren Weckesser, to understand bifurcations of dynamical systems with multiple time scales. Using the  forced van der Pol equation as a case study, we illustrate how canards - solutions that track unstable slow manifolds - play an important role in both bifurcations and chaos. In many situations canards cannot be computed by solving initial value problems, so many of the phenomena that we exhibit are missed by typical simulation studies of multiscale systems.

 

Joint Algebraic Geometry and Number Theory Seminar

Statistical Mechanics Seminar

Topic:       Are electromagnetic ultraviolet cutoffs here to stay?

Presenter:  Michael Kiessling, Rutgers University

Date:         Wednesday, November 6, 2002, Time: 2:00 p.m., Location: Jadwin 343

Abstract:    There are strong indications from nonperturbative QED that its ultraviolet cutoff(s) cannot be removed. Differing expert opinions on what that could mean include (paraphrasing): a) We have not yet seen a proof that it cannot be done. b) A purely electromagnetic theory has to get into conflict with itself at high energies. A consistent theory requires a (supersymmetic) unification of all interactions. c) We have been trying to quantize the wrong classical model. d) We should stop trying to quantize a classical model and look for some radically new ideas, like non-associative algebra.  Each opinion has its own merits, and it should be interesting to find out which one, if any, is correct. In my talk I will review some older results of others and present some new results of my own which, I  believe, open up an entirely new perspective on the issue.

 

Department Colloquium

Topic:      Expander graphs - where Combinatorics and Algebra compete and cooperate

Presenter:  Avi WigdersonIAS and The Hebrew University

Date:          Wednesday, November 6, 2002, Time: 4:30 p.m., Location: Fine Hall 314

Abstract:    Expansion of graphs can be given equivalent definitions in combinatorial and algebraic terms. This is the most basic connection between combinatorics and algebra illuminated by expanders and the quest to construct them. The talk will survey how fertile this connection has been to both fields, focusing on recent results.  In particular, we'll explain the zig-zag product of graphs, how it leads to an elementary combinatorial construction of expanders, and its relation to semi-direct product in groups.

Joint Princeton University/IAS Number Theory Seminar

Topic:        On the sign of Kloosterman sums

Presenter:  Philippe Michel,  IUF and Univ. Montpellier II

Date:          Thursday, November 7, 2002:  Time:  4:30, Location:  TBA

Abstract:    Let $S(1,1;n)$ be the Kloosterman sum of modulus $n$. In a joint work with E. Fouvry, we show that, as $n$ varies over a set of allmost prime integers (ie. more precisely over the set of squarefree integers having at most 23 prime factors) $S(1,1;n)$ takes positive (resp. negative) values infinitely often.This talk will describe the proof and some possible improvements of this result which mixes together, sieve methods (Bombieri's or Selberg's sieve), automorphic forms (Kloostermania) and $l$-adic techniques (Katz's vertical Sato-Tate laws for Kloosterman sums).

PACM Colloquium

Topic:      The Level Set Method-what's in it for you?

Presenter:  Stanley Osher, University of California, Los Angeles

Date:         Monday, November 11, 2002, Time: 4:00 p.m., Location: Fine Hall 214

Abstract:    The level set method for capturing moving fronts was introduced in 1987 by Osher and Sethian. It has proven to be phenomenally successful as a numerical device. For example, typing in "Level Set Methods" on Google's search engine gives roughly 3200 responses.  Applications range from capturing multiphase fluid dynamical flows, to special effects in Hollywood to visualization,image processing, control, epitaxial growth, computer vision and many more. In this talk we shall give an overview of the numerical technology and a few applications.

 

Special Lecture 

Topic:        An Introduction to Quasiconvexity  (Parts I and II - see November 13 for Parts III - VI)

Presenter:   John Ball, Oxford University and IAS

Date:          Tuesday, November 12, 2002:  Time:  2:30 p.m. and 4:00 p.m., Location:  Fine Hall 110

Abstract:    Quasiconvexity is the central convexity condition of the multi-dimensional calculus of variations, but because of the lack of an adequate characterization of quasiconvex functions it remains somewhat mysterious.  The lectures will cover the following topics: a) Definition and examples of quasiconvex functions.  Null Lagrangians and polyconvexity.  Rank-one convexity.  b) Lower semicontinuity and existence of minimizers.  Applications to elasticity.  Quasiconvexity in the interior and at the boundary as necessary conditions for a minimizer.  Partial regularity.  Relaxation.  c) Quasiconvexity and gradient Young measures. Quasiconvex sets of matrices.  Relaxation and the passage from microscales to macroscales.  Examples involving finitely many matrices or energy wells.  Martensitic microstructure.  d) Extensions and applications: higher-order problems, homogenization, quasiregular maps...These lectures precede the conference Quasiconvexity and its Appications (see http://www.mis.mpg.de/conferences/quasiconvexity2002/).  The lectures will be self-contained and assume as little background knowledge as possible.  However, some familiarity with Sobolev spaces and weak convergence in Lp spaces will be an advantage.

PACM Colloquium

Topic:       An Eulerian Method for Multiphase Computations of the Schrodinger Equation

Presenter:  Xiantao Li, PACM, Princeton University

Date:         Monday, November 18, 2002, Time: 4:00 p.m., Location: Fine Hall 214

Abtract:    We present a new numerical method for the computation of the semiclassical limits of the Schrodinger equation. We first use Wigner transform technique to derive a Vlasov equation in the phase space, and then find its solution in the multiphase regime.  By taking moment closure, we obtain the multiphase equations in the physical space. The numerical procedure follows the solution of the Vlasov equation, but only operates in the physical space, which offers great efficiency and simplicity. In addition, we will show some other application of this technique, such as the multivalued solutions of the Euler Poisson system in Klystron.
