Probability Seminar

The probability seminar is a weekly seminar featuring the latest research in pure and applied probability. Speakers include internationally renowned probabilists as well as probabilistic work from related disciplines including computer science and operations research. It also presents graduate students a friendly environment to present their research.

The seminar is held weekly in 1011 Evans on Wednesdays at 3pm, except when otherwise indicated.

Sign up to the department's seminars [at] stat [dot] berkeley [dot] edu (seminars mailing list).

Abstract:
According to a classical result of Bertoin (1998), if the initial data for Burgers equation is a Levy Process with no positive jump, then the same is true at later times and there is an explicit equation for the evolution of the associated Levy measures. In 2010, Menon and Srinivasan published a conjecture for the statistical structure of solutions to scalar conservation laws with certain Markov...

Abstract:
We give an m^{1+o(1)} beta^{o(1)}-time algorithm for generating uniformly random spanning trees in weighted graphs with max-to-min weight ratio beta. In the process, we illustrate how fundamental tradeoffs in graph partitioning can be overcome by eliminating vertices from a graph using Schur complements of the associated Laplacian matrix. Our starting point is the Aldous-Broder algorithm,...

Abstract:
The Heisenberg group ( 3 by 3 upper-triangular matrices with entries in a ring) is a venerable mathematical object. Simple random walk picks one of the bottom two rows at random and adds or substracts it from the row above. I will use Fourier analysis to get sharp results about the long term behavior. For entries in integers mod n, the walk converges to uniform after order n squared steps
