Cyclic group actions on contractible $4$–manifolds

Nima Anvari and Ian Hambleton

Geometry & Topology 20 (2016) 1127–1155

There are known infinite families of Brieskorn homology 3–spheres which can be realized as boundaries of smooth contractible 4–manifolds. In this paper we show that smooth free periodic actions on these Brieskorn spheres do not extend smoothly over a contractible 4–manifold. We give a new infinite family of examples in which the actions extend locally linearly but not smoothly.
