Gromov-Witten invariants and membrane indices of fivefolds via the topological vertex
Yannik Schuler
We conjecture the existence of almost integer invariants governing the all-genus equivariant Gromov-Witten theory of Calabi-Yau fivefolds with a torus action. We prove the conjectu…

Gromov-Witten theory of bicyclic pairs
Michel van Garrel, Navid Nabijou, Yannik Schuler
A bicyclic pair is a smooth surface equipped with a pair of smooth divisors intersecting in two reduced points. Resolutions of self-nodal curves constitute an important special cas…

The log-open correspondence for two-component Looijenga pairs
Yannik Schuler
A two-component Looijenga pair is a rational smooth projective surface with an anticanonical divisor consisting of two transversally intersecting curves. We establish an all-genus…
