| Associativity in quantum cohomology is proven using a gluing formula for Gromov-Witten invariants. The gluing formula underlying orbifold quantum cohomology has additional interesting features. The Gross-Siebert program requires an analogue of quantum cohomology in logarithmic geometry, with underlying gluing formula for punctured logarithmic invariants. I'll attempt to explain how this works and what new subtle features arise. This is based on joint work with Q. Chen, M. Gross and B. Siebert (https://arxiv.org/pdf/2009.07720.pdf). |
