An approach to gauged Gromov-Witten theory

Constantin Teleman (Berkeley)



I will discuss an approach to the construction of 2-dimensional TQFT's associated to a projective manifold with reductive group action, involving K-theory and avoiding stability conditions and the problem of singularities which cause difficulties in the standard approaches. Time permitting, I will also propose a 'gauged mirror model' which enhances the usual mirror dual description to include group actions.
