Jarosław Kędra, Gromov-Witten invariants of the Kodaira-Thurston manifold

Abstract: I will present a computation of the Gromov-Witten invariant counting pseudoholomorphic tori in the Kodaira-Thurston manifold. For a fixed symplectic form such an invariant is always trivial. However, if we allow a topologically nontrivial family of symplectic forms, then it is nonzero and this will be the case in my talk. This is the first example of a computation for a non-Kähler manifold. It is a joint work with Jonny Evans (ETH).
