Extended surgery theory for simply-connected $4 k$ -manifolds

Csaba Nagy

Kreck proved that two $2 q$ -manifolds are stably diffeomorphic if and only if they admit normally bordant normal $(q - 1)$ -smoothings over the same normal $(q - 1)$ -type $(B, I^¾)$ . We sh…

Simple homotopy types of even dimensional manifolds

Csaba Nagy, John Nicholson, Mark Powell

Given a closed $n$ -manifold, we consider the set of simple homotopy types of $n$ -manifolds within its homotopy type, called its simple homotopy manifold set. We characterise it in…
