Hochschild Cohomology and Twisted Complexes on Complex Manifolds
Yue Lin L. Tong, I-Hsun Tsai
We use the theory of twisted resolutions and twisted complexes to give a proof of Kontsevich's claim that Yoneda product corresponds to cup product in a canonical isomorphism from…

Hitchin's connection and differential operators with values in the determinant bundle
Xiaotao Sun, I-Hsun Tsai
Let be a local universal family of smooth curves and be the family of moduli spaces of stable bundles with a fixed determinant on curves. In this paper, we find locally…

Deformation of spherical CR structures and the universal Picard variety
Jih-Hsin Cheng, I-Hsun Tsai
We study deformation of spherical circle bundles over Riemann surfaces of genus > 1. There is a one to one correspondence between such deformation space and the so-called univ…
