Guillem Perarnau Extremal stationary values for directed random graphs In this talk, we will discuss the minimum positive value of the stationary distribution of a random walk on a directed random graph with given (bounded) degrees. While for undirected graphs the stationary distribution is simply determined by the degrees, the graph geometry plays a major role in the directed case. Understanding typical stationary values is key to determining the mixing time of the walk, as shown by Bordenave, Caputo, and…

YEQT XIV: "Load balancing and scheduling for distributed service systems"
Summary Distributed service systems are ubiquitous, from server farms for cloud computing and charging stations for electric vehicles, to checkout lines at supermarkets and ICU beds in hospitals. The size of many of these systems has exploded over the past few years, which has created new challenges in the design of control policies. These new challenges, such as scalability, data locality, and server and task heterogeneity, have fueled a renewed interest in the study of these systems, and accelerated the…
