ABSTRACT | In this talk we show that all knot surgery 4-manifolds E(n)_K are mutually diffeomorphic after a connected sum with CP^2. Hence, by combining a known fact that every simply connected elliptic surface is almost completely decomposable, we conclude that every knot surgery 4-manifold E(n)_K is also almost completely decomposable.
