Jean-Yves Welschinger: Expected topology of a random subcomplex in a simplicial complex

Abstract: I will explain how to bound from above and below the expected Betti numbers of a random subcomplex in a simplicial complex and get asymptotic results under infinitely many barycentric subdivisions. This is a joint work with Nermin Salepci. It complements previous joint works with Damien Gayet on random topology.
