Instanton-Symplectic homology and integral Dehn Surgery – Guillem Cazassus (Institut de Mathématiques de Toulouse)


Sala Seminari (Dip. Matematica).


Motivated by the Atiyah-Floer conjecture, Manolescu and Woodward defined an invariant for closed oriented 3-manifolds called “Instanton-Symplectic homology”. I will explain how they fit into the framework of a “Floer Field Theory” developped by Wehrheim and Woodward, and I will give a Künneth formula for connected sum, and long exact sequences between (a “twisted” version of) the invariants of a surgery triad.
