A counterexample to a global-dimension bound for weighted projective lines
Bochao Kong, Yeqin Liu, Yu Shen
We observe that standard derived equivalences give a counterexample to a conjecture of Kalck on global dimension for weighted projective lines. For the root stack $X=\mathbb{P}^1\l…
A counterexample to Han's conjecture
Bochao Kong, Yeqin Liu, Yu Shen
There is a finite dimensional -algebra with and for .
A counterexample to DG version of Han's conjecture
Yeqin Liu, Yu Shen
In 2004, Han proposed the following conjecture: let be a finite-dimensional -algebra. If for only finitely many , then is smo…
Picard group action on the category of twisted sheaves
Ting Gong, Yeqin Liu, Yu Shen
In this paper, we study the category of twisted sheaves over a scheme . Let be a quasi-coherent sheaf on , and in . We show that the f…
Representations of a class of infinite-dimensional primitive Lie superalgebras
Priyanshu Chakraborty, Yuhui shen, Bin Shu
In [Kac77, Section 5.4] and [Kac 98], V. G. Kac tried to raise, and finished a classification of infinite-dimensional primitive Lie superalgebras. The series with…
Derived Category of certain maximal order on
Yu Shen
We show that the moduli space of -line bundles with minimal second Chern class is a fine moduli space, where is a maximal quaternion order on ramified along…
Morita theory of twisted sheaves on -gerbes of line bundles
Yeqin Liu, Yu Shen
We study Morita theory of twisted sheaves on -gerbes of line bundles . In this context, we find explicit equivalent conditions for when two Azumaya algebras on…
Stability conditions on surface root stacks
Yeqin Liu, Yu Shen
We construct tilt stability conditions on surface root stacks and show that they have support property with respect to the rational Chen-Ruan cohomology.
