Title: Mahler measures, special values and exactness: a periodic journey
Abstract: Born in transcendental number theory, the Mahler measure of polynomials has been in recent years linked
 to the study of special values of L-functions, by the seminal works of Boyd, Deninger and Rodriguez-Villegas. 
 Sometimes, Mahler measures of polynomials in n-variables have been linked to special values associated to objects 
 whose dimension is strictly less than n-1. The aim of this talk, based on joint work in progress with François Brunault,
  is to give a cohomological interpretation of this "drop" in the dimension, which is linked to the notion of "successive exactness", 
  coming from insights of Maillot and Lalín.
