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
