Random Walks on Finite Groups

Markov chains on finite sets are used in a great variety of situations to approximate, understand and sample from their limit distribution. A familiar example is provided by card shuffling methods. From this viewpoint, one is interested in the “mixing time” of the chain, that is, the time at which the chain gives a good approximation of the limit distribution. A remarkable phenomenon known as t...

Diffusion at finite speed and random walks.

Diffusion, which occurs with infinite speed, results from a random walk with steps of finite speed. We resolve this paradox and derive a modified diffusion equation with finite speed.

Current reversal and exclusion processes with history-dependent random walks

A class of exclusion processes in which particles perform history-dependent random walks is introduced, stimulated by dynamic phenomena in some biological and artificial systems. The particles locally interact with the underlying substrate by breaking and reforming lattice bonds. We determine the steady-state current on a ring, and find current-reversal as a function of particle density. This p...

RANDOM WALKS WITH k-WISE INDEPENDENT INCREMENTS

We construct examples of a random walk with pairwise-independent steps which is almost-surely bounded, and for any m and k a random walk with k-wise independent steps which has no stationary distribution modulo m.

Lecture 6 : Random Walks versus Independent Sampling

For many problems it is necessary to draw samples from some distribution D on a typically large set V . In order to do so, one often considers a Markov chain on V whose limiting distribution is D. The efficiency of the sampling algorithm requires the Markov chain to converge quickly. Two famous examples where this approach have been applied successfully are approximation algorithms for the perm...
