"The complex of  HNN-extensions  associated to  the free group of rank n"
Abstract

: 

 In this talk,  we shall discuss the complex of HNN - extensions
associated to the free group F_n  of finite rank n.   We shall sketch a
proof the following result " The group of simplicial automorphisms  of this
complex is isomorphic to the group Out(F_n) of outer automorphisms  of the
free group F_n of rank n.
