Monday, February 6

MATH BIOLOGY SEMINAR
TIME: 2:30 - 3:20 p.m.
ROOM: Ayres 121
SPEAKER: Marco Martinez
TITLE: More on Latin Hypercube Sampling

FIRST ANNUAL LECTURE ON NEW FRONTIERS IN PROBABILITY
TIME: 3:35 – 4:25 p.m.
ROOM: Ayres 405
SPEAKER: Professor Krzysztof Burdzy, University of Washington, Seattle
TITLE: Shy couplings, lion and man, and rubber band domains
ABSTRACT: The talk will be an exciting mixture of probability, metric geometry, differential games and algebraic geometry. (OK, "rubber band domains", in fact, are not a topic in algebraic geometry but I thought that "algebraic geometry" would sound sophisticated.) Shy couplings are pairs of processes that do not come close to each other (ever!). Every well educated person should know whether the lion can catch the man. The most surprising claims will be: (i) Pursuit problems for Brownian particles (which have "infinite" velocity) are related to pursuit problems with bounded velocities; and (ii) It appears that nobody has thought about "rubber band domains" so far, although they are a very natural concept. Joint work with M. Bramson and W. Kendall.

Refreshments available at 3:15 p.m.

Wednesday, February 8

TOPOLOGY SEMINAR
TIME: 2:30 - 3:20 p.m.
ROOM: Ayres G004
SPEAKER: Professor Jim Conant
TITLE: An introduction to the Novikov conjecture
ABSTRACT: I will attempt to introduce all of the necessary topological ingredients to understand Novikov's conjecture in the way it was originally presented by him in a 1970 paper. I will be following the book by Matthias Kreck and Wolfgang Lück.

COLLOQUIUM
TIME: 3:35 p.m.,
ROOM: Ayres 405
SPEAKER: Professor Betsy Stovall, UCLA
TITLE: Scattering for the cubic Klein–Gordon equation in two space dimensions
ABSTRACT: In this talk, we will outline a proof that solutions to the defocusing cubic Klein–Gordon equation utt − Δu + u + u3 = 0, with real-valued initial data u(0) ∈ H 1 (R2 ) and ut (0) ∈ L2 (R2 ), scatter both forward and backward in time. We will also discuss a related result in the focusing case. Along the way, we will explain what we mean by 'scattering,' provide some motivation for the problem, and explain some connections to problems arising in harmonic analysis. This is joint work with Rowan Killip and Monica Vi¸san.

Refreshments available at 3:00 p.m.
