Abstract

I will describe joint work with Bernd Siebert, providing a vast generalization of relative Gromov-Witten invariants. The proper context for these invariants is stable maps from log smooth curves to log smooth target spaces. This includes such cases one might frequently want to work with, such as working relative to a normal crossings divisor, or relative to the toric boundary of a toric variety.
