The geometry of Nekrasov's gauge origami theory
Noah Arbesfeld, Martijn Kool, Woonam Lim
Nekrasov's gauge origami theory provides a (complex) 4-dimensional generalization of the ADHM quiver and its moduli spaces of representations. We describe the origami moduli space…

The virtual K-theory of Quot schemes of surfaces
Noah Arbesfeld, Drew Johnson, Woonam Lim +2
We study virtual invariants of Quot schemes parametrizing quotients of dimension at most 1 of the trivial sheaf of rank N on nonsingular projective surfaces. We conjecture that the…
