Curve counting on the Enriques surface and the Klemm-Mari\~{n} o formula
G Oberdieck - arXiv preprint arXiv:2305.11115, 2023 - arxiv.org
We determine the Gromov-Witten invariants of the local Enriques surfaces for all genera and
curve classes and prove the Klemm-Mari\~{n} o formula. In particular, we show that the …

Derived categories of hyper-Kähler manifolds: extended Mukai vector and integral structure
T Beckmann - Compositio Mathematica, 2023 - cambridge.org
We introduce a linearised form of the square root of the Todd class inside the Verbitsky
component of a hyper-Kähler manifold using the extended Mukai lattice. This enables us to …
