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…

On the mathematics and physics of Mixed Spin P-Fields
Huai-Liang Chang, Jun Li, Wei-Ping Li +1
We outline various developments of affine and general Landau Ginzburg models in physics. We then describe the A-twisting and coupling to gravity in terms of Algebraic Geometry. We…
