Abstract: 

The Cremona dimension of a finite group G is the minimal dimension of a rationally connected variety which admits a faithful action of G.  In this talk, based on joint work with Giulio Bresciani and Angelo Vistoli, I will discuss new lower bounds on the Cremona dimension of a finite p-group.
