Growth, isoperimetry and Liouville property for random walks on groups
2:00pm|Simonyi Hall 101 and Remote Access - see Zoom link below

In a joint work with Tianyi Zheng we show that the growth function of the first Grigorchuk group satisfies \[ \ln \ln v_n/\ln v_n = a, \] where $a = \log 2/\log x$, $x$ being a positive root of the polynomial $x^3-x^2-2x-4$. This is done by...

Support Varieties for Modular Representations
2:00pm|Simonyi Hall 101 and Remote Access - see Zoom link below

We present an overview of elementary methods to study extensions of modular representations of various types of "groups". We shall begin by discussing actions of an elementary abelian $p$-group, $E = (Z/p)^r$, on finite dimensional vector spaces...
