A note on Akbulut corks

Research output: Contribution to journalArticle

3 Scopus citations


We prove that the involution on the boundary ∑ of the Akbulut cork relating blown up elliptic surfaces to completely decomposable manifolds acts non-trivially on the Floer homology of ∑. We also show that ∑ provides an example of an irreducible manifold with non-zero boundary operator in its Floer chain complex.
