講演題目:"Equivalence between embedded contact homology and Heegaard-Floer homology via open book decompositions"

Abstract: In a work in common with Paolo Ghiggini and Ko Honda, we exibit an isomorphism between Heegaard Floer homology and embedded contact homology for any contact manifold of dimension three $(M,\xi )$. It is constructed from an open book decomposition of $M$ supporting $\xi$.
