Reverse engineering small 4-manifolds
Ronald Fintushel, B. Doug Park, Ronald J. Stern
Abstract
We introduce a general procedure called `reverse engineering' that can be used to construct infinite families of smooth 4-manifolds in a given homeomorphism type. As one of the applications of this technique, we produce an infinite family of pairwise nondiffeomorphic 4-manifolds homeomorphic to CP2#3(-CP2).
