A Cohomological field theory (CohFT) is an algebraic structure underlying the properties of the Gromov-Witten invariants and quantum cohomology of projective varieties. I will talk about a CohFT associated to a holomorphic function F with an isolated singularity and a … Continue reading Colloquium: Tuesday, February 27, 2 pm. Speaker: Arkady Vaintrob (Oregon).
