"Free Actions on Products of Spheres at High
Dimensions"

By

OSMAN BERAT OKUTAN

(Bilkent
University)

Abstract:  Rank
conjecture states that if G=(Z/p)^r acts freely on a
product of spheres S^{n_1} x ... x S^{n_k}, then
r<=k. In this talk we will prove a special case of this conjecture where the
action is cellular and dimensions of spheres are large enough while the
differences between  the dimensions of spheres are
bounded by a fixed number.
