A Generalized vanishing theorem for Blow-ups of Quasi-smooth Stacks
Yu Zhao
We prove a generalized vanishing theorem for certain quasi-coherent sheaves along the derived blow-ups of quasi-smooth derived Artin stacks. We give four applications of the genera…
A Note on the Strict Transformation of an Effective Cartier Divisor
Yu Zhao
Let be an effective Cartier divisor of a smooth variety . Let , be a set of pairwise disjoint smooth subvarieties in such that their union c…
Symmetry Fractionalized (Irrationalized) Fusion Rules and Two Domain-Wall Verlinde Formulae
Yu Zhao, Hongyu Wang, Yuting Hu +1
We investigate the composite systems consisting of topological orders separated by gapped domain walls. We derive a pair of domain-wall Verlinde formulae, that elucidate the connec…
Derived Blow-ups and Birational Geometry of Nested Quiver Varieties
Yu Zhao
Given a quiver, Nakajima introduced the quiver variety and the Hecke correspondence, which is a closed subvariety of Cartesian products of quiver varieties. In this paper, we consi…
Desingulization of Quasi-smooth Derived Schemes and Virtual Fundamental Classes
Yu Zhao
We prove a desingularization theorem for the quasi-smooth derived scheme, in the sense of Hekking. We also propose the conjecture that the K-theoretic integration of the virtual fu…
