Perfect Morse functions and exotic S^2 x S^2's

Geometric Topology 2010-10-14 v2

Abstract

The main theorem of the paper shows that a smooth manifold which is homeomorphic to S^2xS^2 and has nonvanishing Ozsvath-Szabo invariant does not admit a perfect Morse function. I am withdrawing the paper because it is unclear to me if such a manifold exists.
