Finite group actions on 4-manifolds and equivariant bundles
Nima Anvari, Ian Hambleton
Given a 4-manifold with a homologically trivial and locally-linear cyclic group action, we obtain necessary and sufficient conditions for the existence of equivariant bundles. The…

Cyclic Branched Coverings of Brieskorn Spheres Bounding Acyclic 4-Manifolds
Nima Anvari, Ian Hambleton
We show that standard cyclic actions on Brieskorn homology 3-spheres with non-empty fixed set do not extend smoothly to any contractible smooth 4-manifold it may bound. The quotien…

A Splitting Formula in Instanton Floer Homology
Nima Anvari
In a recent paper, Lin, Ruberman and Saveliev proved a splitting formula expressing the Seiberg-Witten invariant of a smooth -manifold with rational homology of $S^1…
