On 2-knots and connected sums with projective planes

Abstract

In this paper, we generalize a result of Satoh to show that for any odd natural nn, the connected sum of the nn-twist spun sphere of a knot KK and an unknotted projective plane in the 4-sphere is equivalent to the same unknotted projective plane. We additionally provide a fix to a small error in Satoh's proof of the case that KK is a 2-bridge knot.
