SUMMARY:Homotopy type of the free factor complex - Radhika Gupta (Technion

DESCRIPTION:The mapping class group of a surface acts on the curve complex
  which is known to be homotopy equivalent to a wedge of spheres. In this t
 alk\, I will define the 'free factor complex'\, an analog of the curve com
 plex\, on which the group of outer automorphisms of a free group acts. Thi
 s complex has many similarities with the curve complex. I will present the
  result (joint with Benjamin Br&uuml\;ck) that the free factor complex is 
 also homotopy equivalent to a wedge of spheres.
