 Orateur(s) Penka Georgieva - IMJ-PRG, Titre A Klein TQFT : the local real Gromov-Witten theory of curves Date 03/12/2019 Horaire 14:00 à 15:00 Résume I will explain how the local real GW theory of curves gives rise to a 2-dimensional Klein TQFT defined on an extension of the category of unorientable surfaces. We use this structure to completely solve the theory by providing a closed formula for the local real GW invariants in terms of representation theoretic data. As a corollary we obtain the local version of the real Gopakumar-Vafa formula. In the case of the resolved conifold the partition function of the real GW invariants agrees with that of the SO/Sp Chern-Simons theory on $S^3$.
