On automorphisms of high-dimensional solid tori

Abstract

We study the infinite generation in the homotopy groups of the group of diffeomorphisms of $S^1\times D^{2n-1}$, for $2n\ge 6$, in a range of degrees up to $n-2$. Our analysis relies on understanding the homotopy fibre of a linearisation map from the plus-construction of the classifying space of certain space of self-embeddings of stabilisations of this manifold to a form of Hermitian $K$-theory of the integral group ring of ${\pi }_1(S^1)$. We also show that these homotopy groups vanish rationally.
