The positive mass theorem under a spectral scalar curvature bound on spin manifolds

Xiangsheng Wang

On spin manifolds, we give a proof of Brendle and Wang's refined positive mass theorem using the Dirac operator method. In the course of this proof, we discuss the origin of the sp…

Comparison of Kähler quotients of torus actions

Xiangsheng Wang, Xiangdong Yang

Let be a torus with the complexification and a compact Kähler Hamiltonian -manifold with the moment map such that acts on…

Generalized moment maps, reduction and complex quotients

Yi Hu, Xiangsheng Wang

In this note, we introduce the concept of momentumly closed forms. A non-degenerate momentumly closed two-form and its generalized moment map are the generalization of two well-kno…

The complex hyperbolic form as a Weil-Petersson form

Xiangsheng Wang

For the moduli space of the punctured spheres, we find a new equality between two symplectic forms defined on it. Namely, by treating the elements of this moduli space as the singu…

A new Weyl group action related to the quasi-classical Gelfand-Graev action

Xiangsheng Wang

We construct a Weyl group action on the DKS type varieties, a certain class of varieties associated with quivers. As a result, on some special DKS type varieties, we can give a qui…

Elliptic boundary value problem on non-compact -manifolds

Xiangsheng Wang

In this paper, an equality between the Hochs-Mathai type index and the Atiyah-Patodi-Singer type index is established when the manifold and the group action are both non-compact, w…
