Local monodromy, Behrend function and Hilbert scheme of points on
Yunfeng Jiang
We prove a criteria for the Behrend function values on the Hilbert scheme of -points on $\C^3$ from local monodromy and the Denef--Loeser's Lefschetz trace formula of jet spaces…
Rational -systems for integrable spin chains without symmetry
Yunfeng Jiang, Yi-Chao Liu, Yuan Miao +1
The -system is an efficient method for finding complete physical solutions of Bethe ansatz equations, but so far its application has been confined to systems possessing s…
Equivariant deformation of minimally elliptic singularities
Sagnik Das, Yunfeng Jiang
We study certain equivariant deformation components of minimally elliptic surface singularities under finite group actions. Interesting examples include cyclic quotients of simple…
The quantum cohomology of moduli space of $\PGL_2$-bundles on curves
Sagnik Das, Yunfeng Jiang, Hsian-Hua Tseng
We calculate the quantum cohomology of the moduli space of stable $\PGL_2$-bundles over a smooth curve of genus .
Smoothing of surface singularities via equivariant smoothing of lci covers
Yunfeng Jiang
We provide some results of the smoothing of surface singularities by Looijenga-Wahl and study smoothing of isolated surface singularities induced by equivariant smoothing of locall…
On the Bogomolov-Gieseker inequality for tame Deligne-Mumford surfaces
Yunfeng Jiang, Promit Kundu, Hao Max Sun
We generalize the Bogomolov-Gieseker inequality for semistable coherent sheaves on smooth projective surfaces to smooth Deligne-Mumford surfaces. We work over positive characterist…
The moduli space of stable coherent sheaves via non-archimedean geometry
Yunfeng Jiang
We provide a construction of the moduli space of stable coherent sheaves in the world of non-archimedean geometry, where we use the notion of Berkovich non-archimedean analytic spa…
