Groups & Dynamics seminar. Mark Sapir (Vanderbilt): S-machines and their applications

Title: S-machines and their applications
Abstract: I will discuss applications of S-machines which were first introduced in 1996. The applications include
* Description of possible Dehn functions of groups
* Various Higman-like embedding theorems
* Finitely presented non-amenable torsion-by-cyclic groups
* Aspherical manifolds containing expanders
* Groups with quadratic Dehn functions and undecidable conjugacy problem
