DESCRIPTION:Title: <a href="https://researchseminars.org/talk/TQFT/21/">Kl
 ein TQFT and real Gromov-Witten invariants</a>\nby Penka Georgieva (Sorbon
 ne Université) as part of Topological Quantum Field Theory Club (IST\, Li
 sbon)\n\n\nAbstract\nIn this talk I will explain how the Real Gromov-Witte
 n theory of local 3-folds with base a Real curve gives rise to an extensio
 n of a 2d Klein TQFT. The latter theory is furthermore semisimple which al
 lows for complete computation from the knowledge of a few basic elements w
 hich can be computed explicitly. As a consequence of the explicit expressi
 ons we find in the Calabi-Yau case\, we obtain the expected Gopukumar-Vafa
  formula and relation to SO/Sp Chern-Simons theory.\n
