A remark on the isotopy classes of diffeomorphisms of lens spaces

Wu-Chung Hsiang and Bjørn Jahren

Vol. 109 (1983), No. 2, 411–423
Abstract

Let L be a lens space of dimension at least 5 and with fundamental group of odd order. In this paper we reduce the computation of π0(Diff L) to algebraic K-theory and homotopy theory. The approach is via parametrized surgery theory, as developed by the first author and R. Sharpe.
