Exotic Smooth Structures on Small 4-Manifolds

Anar Akhmedov, B. Doug Park

Published 2007-01-24, updated 2007-03-12Version 4

Let M be either CP^2#3CP^2bar or 3CP^2#5CP^2bar. We construct the first example of a simply-connected symplectic 4-manifold that is homeomorphic but not diffeomorphic to M.
