Gromov-Witten/Hilbert versus AdS3/CFT2 Correspondence

W Lerche - arXiv preprint arXiv:2310.15237, 2023 - arxiv.org
We consider the boundary dual of AdS3xS3xK3 for NS5-flux Q5= 1, which is described by a
sigma model with target space given by the d-fold symmetric product of K3. Building on …

[HTML][HTML] Marked relative invariants and GW/PT correspondences

G Oberdieck - Advances in Mathematics, 2024 - Elsevier
We introduce marked relative Pandharipande-Thomas (PT) invariants for a pair (X, D) of a
smooth projective threefold and a smooth divisor. These invariants are defined by …

Holomorphic anomaly equations for the Hilbert scheme of points of a K3 surface

G Oberdieck - Geometry & Topology, 2024 - msp.org
We conjecture that the generating series of Gromov–Witten invariants of the Hilbert schemes
of n points on a K3 surface are quasi-Jacobi forms and satisfy a holomorphic anomaly …

Gopakumar–Vafa type invariants of holomorphic symplectic 4-folds

Y Cao, G Oberdieck, Y Toda - Communications in Mathematical Physics, 2024 - Springer
Abstract Using reduced Gromov–Witten theory, we define new invariants which capture the
enumerative geometry of curves on holomorphic symplectic 4-folds. The invariants are …

Quasimaps to moduli spaces of sheaves on a surface

D Nesterov - Forum of Mathematics, Sigma, 2024 - cambridge.org
In this article, we study quasimaps to moduli spaces of sheaves on a $ K3 $ surface S. We
construct a surjective cosection of the obstruction theory of moduli spaces of $\epsilon …

Gromov–Witten theory and Noether–Lefschetz theory for holomorphic-symplectic varieties

G Oberdieck - Forum of Mathematics, Sigma, 2022 - cambridge.org
We use Noether–Lefschetz theory to study the reduced Gromov–Witten invariants of a
holomorphic-symplectic variety of-type. This yields strong evidence for a new conjectural …

Pandharipande-Thomas theory of elliptic threefolds, quasi-Jacobi forms and holomorphic anomaly equations

G Oberdieck, M Schimpf - arXiv preprint arXiv:2308.09652, 2023 - arxiv.org
Let $\pi: X\to B $ be an elliptically fibered threefold satisfying $ c_3 (T_X\otimes\omega_X)=
0$. We conjecture that the $\pi $-relative generating series of Pandharipande-Thomas …

On quasimap invariants of moduli spaces of Higgs bundles

D Nesterov - Moduli, 2024 - cambridge.org
We compute odd-degree genus 1 quasimap and Gromov–Witten invariants of moduli
spaces of Higgs. We also compute certain invariants for all prime ranks. This proves some …
