Tropical super Gromov-Witten invariants

Artan Sheshmani, Shing-Tung Yau, Benjamin Zhou

We show that super Gromov-Witten invariants can be defined and computed by methods of tropical geometry. When the target is a point, the super invariants are descendant invariants…

Higher genus Gromov-Witten invariants from projective bundles on smooth log Calabi-Yau pairs

Benjamin Zhou

Let $(X, E)$ be a smooth log Calabi-Yau pair consisting of a smooth Fano surface $X$ and a smooth anticanonical divisor $E$ . We obtain certain higher genus local Gromov-Witten invar…

Enumerative Geometry of Quantum Periods

Tim GrÃ¤fnitz, Helge Ruddat, Eric Zaslow +1

We interpret the $q$ -refined theta function $ϑ_{1}$ of a log Calabi-Yau surface $(P, E)$ as a natural $q$ -refinement of the open mirror map, defined by quantum period…
