KLR-Schur algebra of coherent sheaves on the projective line: Tilting and PBW bases
Olivier Schiffmann, Fang Yang
We begin the study of Khovanov-Lauda-Rouquier type algebras associated to moduli stacks of coherent sheaves on smooth projective curves. We consider the case of and…
Degenerations in graded quiver varieties and in derived categories of Dynkin quivers
Alessandro Contu, Fang Yang
For any acyclic quiver, Keller-Scherotzke provided a stratifying functor from the category of finite-dimensional modules of the singular Nakajima category to the derived category o…
Quantum cluster algebras associated to weighted projective lines
Fan Xu, Fang Yang
Let be a weighted projective line. We define the quantum cluster algebra of and realize its sp…
Applications of spherical twist functors to Lie algebras associated to root categories of preprojective algebras
Fan Xu, Fang Yang
Let be the preprojective algebra of a finite acyclic quiver of non-Dynkin type and be the bounded derived category of finite dimensional nilpote…
