DESCRIPTION:Stéphane Saboureau\, Univ. Paris-Est Créteil\nThe volume ent
 ropy of a finite simplicial complex X with a length metric is defined as t
 he exponential growth rate of the volume of balls in its universal cover. 
 The infimum of the volume entropy over all metrics on X of unit volume is 
 a topological invariant\, called the minimal volume entropy. A problem of 
 central importance is to determine under which topological assumption the 
 minimal volume entropy of a closed manifold or of a finite simplicial comp
 lex is nonzero. We will present various results around this problem. Joint
  work with Ivan Babenko.
