On the monopole Lefschetz number of finite order diffeomorphisms

Jianfeng Lin, Daniel Ruberman, Nikolai Saveliev

Let $K$ be a knot in an integral homology 3-sphere $Y$ , and $Σ$ the corresponding $n$ -fold cyclic branched cover. Assuming that $Σ$ is a rational homology sphere (which is always t…

Isotopy of the Dehn twist on K3#K3 after a single stabilization

Jianfeng Lin

Kronheimer-Mrowka recently proved that the Dehn twist along a 3-sphere in the neck of $K 3# K 3$ is not smoothly isotopic to the identity. This provides a new example of self-diffeom…
