Motivated by today’s cloud computing capabilities in large server farms, we present a queueing
model where jobs are split into a number of pieces which are then randomly routed to…

In this talk, we study two different diffusion models on the random graphs. In the first part, we
consider first passage percolation. We analyze the impact of the edge weights on distances
in…

We analyze the efficiency of particular Markov chain methods used in Bayesian statistics, giving some of the first meaningful bounds on the…

Tridiagonal matrices appear almost everywhere (like 2nd order differential operators).This talk grew out of four very different applications: 1. (positive definite) Completion to maximum…
