Доповідач: Насір Ганіходжаєв (Інститут математики, Ташкент, Узбекістан) Тема: Phase Diagrams of Lattice Models with Competing Interactions Тези. The existence of competing interactions lies at the heart of a variety of original phenomena in magnetic systems, ranging from the spin-glass transitions found in many disordered materials to the modulated phases with an infinite number of commensurate regions, that are […]

Доповідач: Andrea Ottolini (Університет Вашингтону) Тема: Hitting times in random graphs Тези. I will discuss a general approach to derive nearly-exact formulas for average hitting times in large graphs. As a main example, we will consider the case of the stochastic block model with two communities, though the idea is much more general. Time permitting, I will explain the […]
