Aaron Pixton (MIT), Cycle-quasimodularity of elliptic curve invariants


Abstract: Okounkov and Pandharipande proved that Gromov-Witten invariants of an elliptic curve are coefficients of quasimodular forms. I will explain how to lift this quasimodularity to the level of cycles (on the moduli space of stable curves). This is joint work with Georg Oberdieck.
