Betti bounds for the Stanley-Reisner ring of a stellar subdivision
The talk will be about recent joint work with Janko Boehm (Kaiserslautern) which uses unprojection theory to give bounds for the betti numbers of the Stanley-Reisner ring of a stellar subdivision of a Gorenstein* simplicial complex.
