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…

On the Chern filtration for the moduli of bundles on curves
Woonam Lim, Miguel Moreira, Weite Pi
We introduce and study the Chern filtration on the cohomology of the moduli of bundles on curves. This can be viewed as a natural cohomological invariant defined via tautological c…

Cohomology rings of the moduli of one-dimensional sheaves on the projective plane
Yakov Kononov, Woonam Lim, Miguel Moreira +1
We initiate a systematic study on the cohomology rings of the moduli stack of semistable one-dimensional sheaves on the projective plane. We introduce a set o…
