Speaker: Eyal Lubetzky
Title: Random walks on the random graph
Date and time: April 24, 1:00 p.m. (light refreshments at 12:45 p.m.)
Venue: WWH 1302

Abstract

We study random walks on the giant component of the Erdős-Rényi random graph $G(n,p)$ where $p= lambda / n$ for $lambda > 1$ fixed. The mixing time from a worst starting point was shown by Fountoulakis and Reed, and independently by Benjamini, Kozma and Wormald, to have order $log^2 n$. We prove that starting from a uniform vertex (equivalently, from a fixed vertex conditioned to belong to the giant) both accelerates mixing to $O(log n)$ and concentrates it (the cutoff phenomenon occurs). Joint work with N. Berestycki, Y. Peres and A. Sly.

About this seminar

This seminar is meant to benefit young mathematicians, particularly graduate students and postdocs.
It aims to accomplish the following: The research talks should be fairly introductory and accessible to students and non-specialists in the audience.
