Title: Holomorphic anomaly equations of elliptic fibrations and quasi-Jacobi forms
Abstract: Generating series of Gromov-Witten invariants of Calabi-Yau threefolds satisfy conjecturally two properties: They live in a finitely generated algebra of quasi-modular forms (finite generation) and satisfy a holomorphic anomaly equation. I will discuss joint work with Pixton which extends (with evidence) this conjecture to elliptic fibrations of any dimension which are possibly non-Calabi Yau. The finitely generated ring here is the algebra of quasi-Jacobi forms.
