摘 要：

Discrete conformal structure on polyhedral manifolds is a discrete analogue of the conformal structure on Riemannian manifolds. There are several different types of discrete conformal structures on surfaces, most of which were invented and studied individually in the past. The generic notion of discrete conformal structures on polyhedral surfaces was introduced recently independently byGlickensteinand Thomas from Riemannian geometry perspective and by Zhang-Guo-Zeng-Luo-Yau-Gu fromBobenko-Pinkall-Springborn'sobservation on the relationships of vertex scaling on polyhedral surfaces and 3-dimensional hyperbolic geometry. In this talk, we will report some recent progress on rigidity and deformation of generic discrete conformal structures on polyhedral surfaces.
