A survey on constructing free actions on products of spheres"

Ergün Yalçın (Bilkent)

 

Abstract: I will give a survey of problems and recent results on
constructing free actions on products of spheres. The rank conjecture, due
to Benson and Carlson, states that a finite group G acts freely and
cellularly on a finite complex X homotopy equivalent to a product of k
spheres if and only if the rank of G is less than or equal to k. This
conjecture is known to be true for k=1 by classical Smith theory and by a
theorem of Swan. For k=2 it is proved by Adem and Smith, and Jackson that if
a rank two finite group does not involve the group Qd(p) for any odd prime
p, then it acts freely and cellularly on a finite complex X homotopy
equivalent to a product of two spheres. I will discuss what is known for the
remaining case G=Qd(p). The most recent results that I will present are
joint work with Cihan Okay. I will also mention some earlier work joint with
Ozgun Unlu and with Ian Hambleton.
