Exotic smooth structures on $CP^2#5{\bar CP^2}$

Jongil Park, Andras I Stipsicz, Zoltan Szabo

Published 2004-12-10, updated 2005-05-09Version 3

Motivated by a construction of Fintushel and Stern, we show that the topological 4--manifold $CP^2#5{\bar CP^2}$ supports infinitely many distinct smooth structures.

Comments: 14 pages, 4 figures; details of computation of Seiberg-Witten invariants is added
