Irregular vanishing on
Huai-Liang Chang, Sanghyeon Lee, Jun Li
In this paper, we describe Mixed-Spin-P(MSP) fields for a smooth CY 3-fold . Then we describe fixed loci of the mo…
A boundedness theorem for principal bundles on curves
Huai-Liang Chang, Shuai Guo, Jun Li +2
Let be a reductive group acting on an affine scheme . We study the set of principal -bundles on a smooth projective curve such that the associated -bundle…
Stability conditions in the mathematical Gauged Linear Sigma Model
Huai-Liang Chang, Shuai Guo, Jun Li +2
The theory of Mixed-Spin-P (MSP) fields was introduced by Chang-Li-Li-Liu for the quintic threefold, aiming at studying its higher-genus Gromov-Witten invariants. Chang-Guo-Li has…
Moduli of high rank Vector bundles over Surface
David Gieseker, Jun Li
This is the revised version of our previous preprint. In this paper, we establish a generic smoothness result for moduli space of semistable sheaves of arbitrary rank over surfaces…
