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…

Higher rank DT/PT wall-crossing in Bridgeland stability
Marcos Jardim, Jason Lo, Antony Maciocia +1
We prove that the Gieseker moduli space of stable sheaves on a smooth projective threefold of Picard rank 1 is separated from the moduli space of PT stable objects by a single…

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…
