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…

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…
