Gromov-Witten theory of elliptic orbifold P1
and quasi-modular forms
Abstract:
Gromov-Witten invariants counts the number
of pseudo-holomorphic curves. One often write them
in terms of generating functions. Occasionally, it
posses some very beautiful properties such as being
a quasi-modular form. In the talk, we will explain
this phenomenon for elliptic orbifold P^1. This is
joint work with Milanov, Krawitz and Shen.
