The volume entropy of a finite simplicial complex X with a length metric is defined as the 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 complex is nonzero. We will present various results around this problem. Joint work with Ivan Babenko.
