Morita theory of twisted sheaves on $μ_{n}$ -gerbes of line bundles

Yeqin Liu, Yu Shen

We study Morita theory of twisted sheaves on $μ_{n}$ -gerbes of line bundles $X$ . 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.
