In 2008, Klemm–Pandharipande defined Gopakumar–Vafa type invariants of a Calabi–Yau 4-folds $X$ using Gromov–Witten theory. Recently, Cao–Maulik–Toda proposed a conjectural description of these invariants in terms of stable pair theory. When $X$ is the total space of the sum of two line bundles over a surface $S$, and all stable pairs are scheme theoretically supported on the zero section, we express stable pair invariants in terms of intersection numbers on Hilbert schemes of points on $S…

Orientations on the moduli stack of compactly supported perfect complexes over a non-compact Calabi--Yau 4-fold
We consider a Calabi--Yau 4-fold $(X,\omega)$, where $X$ is quasi-projective and $\omega$ is a nowhere vanishing section of its canonical bundle $K_X$. The (derived) moduli stack of compactly…

Gopakumar-Vafa type invariants of holomorphic symplectic 4-folds
Using reduced Gromov-Witten theory, we define new invariants which capture the enumerative geometry of curves on holomorphic symplectic 4-folds. The invariants are analogous to the BPS counts of…

K-Theoretic DT/PT Correspondence for Toric Calabi–Yau 4-Folds
Recently, Nekrasov discovered a new “genus” for Hilbert schemes of points on $${\mathbb {C}}^4$$ C 4 . We extend its definition to Hilbert schemes of curves and moduli spaces of stable…
Correspondence of Donaldson-Thomas and Gopakumar-Vafa invariants on local Calabi-Yau 4-folds over V_5 and V_22
We compute Gromov-Witten (GW) and Donaldson-Thomas (DT) invariants (and also descendant invariants) for local CY 4-folds over Fano 3-folds, V5 and V22 up to degree 3. We use torus localization for GW…
Wall-crossing for zero-dimensional sheaves and Hilbert schemes of points on Calabi--Yau 4-folds
We define a vertex algebra on the moduli stack of the auxiliary abelian category of pairs to give a precise formulation of the wall-crossing conjecture for Calabi–Yau 4-folds proposed by…
Stable maps to Looijenga pairs: orbifold examples
In [15] we established a series of correspondences relating five enumerative theories of log Calabi–Yau surfaces, i.e. pairs (Y,D) with Y a smooth projective complex surface and D = D1 + · · ·+Dl an…
