In this work, we show the intrinsic relations between optimal transportation and convex geometry, especially the variational approach to solve Alexandrov problem: constructing a convex polytope with prescribed …
Colon Flattening Using Heat Diffusion Riemannian Metric
In mathematics, conformal means "angle preserving". Conformal structure is a specail atlas of the surface, such that angles among tangentvectors can be coherently defined on different local coordinate systems. Furthermore, concepts in complex anylasis can be defined on the surface via conformal structure. … See more A surface with a conformal structure is called a Riemann surface. All metric surfaces are Riemann surfaces. The image illustrates the … See more Surface uniformization means that all metric surfaces can be conformally mapped to one of the three canonical domains, the sphere, the plane and the hyperbolic space. The figures show the uniformization for … See more WebJun 22, 2024 · Authors: Xianfeng GU (Stony Brook University)*; Yalin Wang (Arizona State University); Dongsheng An (Stony Brook University); Min Zhang (Brigham and Women’s Hospital, Harvard Medical School); ...
