报告内容介绍:
The geometric average of a polynomial over the real unit torus is a way to measure the polynomial's complexity content, introduced by Mahler to study questions in transcendence theory. In this talk, we will see how this quantity, and its p-adic analogues, are related to heights in Diophantine geometry, entropies of dynamical systems, and growth rates of invariants associated to towers of knots and graphs, which are reminiscent of classical formulas in Iwasawa theory. Moreover, we will see how the study of small, univariate Mahler measures leads naturally to the study of multivariate ones, which are conjecturally connected to special values of L-functions. This is based on joint works with François Brunault, Antonin Guilloux, Mahya Mehrabdollahei and Daniel Vallières.
