Mixing for some Z-extensions of suspension flows.
Abstract: In the first part of the talk, I will recall results on the local limit theorem for Z and Z^2 extensions of suspension flows, which in particular imply mixing for these flows. In the second part, I will argue that techniques developed in the renewal theory for operators can be used to obtain mixing for a large class of Z extensions of suspension flows.
