D-critical locus structure on the Hilbert schemes of some local toric Calabi-Yau threefolds
Sheldon Katz, Yun Shi
The notion of a d-critical locus is an ingredient in the definition of motivic Donaldson-Thomas invariants by [BJM19]. In this paper we show that there is a d-critical locus struct…

Stability and the deformed Hermitian-Yang-Mills equation
Tristan C. Collins, Yun Shi
We survey some recent progress on the deformed Hermitian-Yang-Mills (dHYM) equation. We discuss the role of geometric invariant theory (GIT) in approaching the solvability of the d…
