Expected topology of a random subcomplex in a simplicial complex

By Jean-Yves Welschinger

Appears in collection : Perspectives in real geometry / Perspectives en géométrie réelle

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.
