Abstract

In this article we prove that, if XX is a smooth 44-manifold containing an embedded double node neighborhood, all knot surgery 44-manifolds XKX_K are mutually diffeomorphic to each other after a connected sum with CP2\mathbb{CP}^2. Hence, by applying to the simply connected elliptic surface E(n)E(n), we also show that every knot surgery 44-manifold E(n)KE(n)_K is almost completely decomposable.
