Stability of the Cotangent Bundle on Surfaces with Ample Canonical Class
Tristan C. Collins, Jason Lo, Yun Shi +1
In this article, we study the Bridgeland stability of the cotangent bundle on K3 surfaces and surfaces with ample canonical class. On a surface with ample canonical class ,…
Bridgeland/Weak Stability Conditions under Spherical Twist Associated to A Torsion Sheaf
Tristan C. Collins, Jason Lo, Yun Shi +1
In this paper, we study the action of an autoequivalence, the spherical twist associated to a torsion sheaf, on the standard Bridgeland stability conditions and a generalized weak…
Weak Stability Conditions as Limits of Bridgeland Stability Conditions
Tristan C. Colllins, Jason Lo, Yun Shi +1
In this paper, we give a definition of weak stability condition on a triangulated category. The difference between our definition and existing definitions is that we allow objects…
Moduli of sheaves on fourfolds as derived Lagrangian intersections
Nachiketa Adhikari, Yun Shi
We show that any -shifted symplectic derived scheme (of finite type over an algebraically closed field of characteristic zero) is locally equivalent to the deriv…
