Dissolving knot surgered 4-manifolds by classical cobordism arguments.

The purpose of this note is to show that classical cobordism arguments, which go back to the pioneering works of Mandelbaum and Moishezon, provide quick and unified proofs of any knot surgered compact simply-connected 4-manifold becoming diffeomorphic to after a single stabilization by connected summing with or , and almost complete decomposability of for many almost completely decomposable , such as the elliptic surfaces.
