Abstract

A cutting and pasting operation on a P2P^2-knot SS in a 44-manifold is called the Price twist. The Price twist for the 44-sphere S4S^4 yields at most three 44-manifolds up to diffeomorphism, namely, the 44-sphere S4S^4, the other homotopy 44-sphere ΣS(S4)\Sigma_{S}(S^4) and a non-simply connected 44-manifold τS(S4)\tau_{S}(S^4). In this paper, we study some properties and diffeomorphism types of τS(S4)\tau_{S}(S^4) for P2P^2-knots SS of Kinoshita type.
