About me
Email: shenyu5 at msu dot edu
I am a graduate student in the Department of Mathematics at Michigan State University, working under professor Rajesh Kulkarni.
My research interest is algebraic geometry, particularly in noncommutative algebras, Brauer groups, derived categories, and Bridgeland stability conditions. Recently, I have been interested in proper DG categories.
Research
Stability conditions on surface root stacks (joint with Yeqin Liu).
Derived category of certain maximal order on ℙ^{2}.
Morita theory of twisted sheaves on \mu_{n} gerbes of line bundles (joint with Yeqin Liu).
Picard group action on the category of twisted sheaves (joint with Ting Gong, and Yeqin Liu).
A moduli interpretation of curves in the intermediate Jacobian of conic bundles.
A counterexample to DG version of Han's conjecture (joint with Yeqin Liu).
On proper finite-cell DG algebras (joint with Yeqin Liu).
