[1912.01187] The Gauss-Bonnet formula for a conformal metric …
In the mathematical field of differential geometry, the Gauss–Bonnet theorem (or Gauss–Bonnet formula) is a fundamental formula which links the curvature of a surface to its underlying topology. In the simplest application, the case of a triangle on a plane, the sum of its angles is 180 degrees. The … See more Suppose M is a compact two-dimensional Riemannian manifold with boundary ∂M. Let K be the Gaussian curvature of M, and let kg be the geodesic curvature of ∂M. Then See more Sometimes the Gauss–Bonnet formula is stated as $${\displaystyle \int _{T}K=2\pi -\sum \alpha -\int _{\partial T}\kappa _{g},}$$ where T is a geodesic triangle. Here we define a "triangle" on M to be a simply connected region … See more There are several combinatorial analogs of the Gauss–Bonnet theorem. We state the following one. Let M be a finite 2-dimensional pseudo-manifold. Let χ(v) denote the number … See more In Greg Egan's novel Diaspora, two characters discuss the derivation of this theorem. The theorem can be used directly as a system to control sculpture. For example, in work by Edmund Harriss in the collection of the See more The theorem applies in particular to compact surfaces without boundary, in which case the integral $${\displaystyle \int _{\partial M}k_{g}\,ds}$$ can be omitted. It states that the total Gaussian curvature … See more A number of earlier results in spherical geometry and hyperbolic geometry, discovered over the preceding centuries, were subsumed as … See more The Chern theorem (after Shiing-Shen Chern 1945) is the 2n-dimensional generalization of GB (also see Chern–Weil homomorphism). The See more WebLet G be an infinite graph embedded in a closed 2-manifold, such that each open face of the embedding is homeomorphic to an open disk and is bounded by finite number of edges. For each vertex x of G, define the combinatorial curvature $$\\Phi_G(x) = 1 - \\... fancy red kimono

WebApr 22, 2009 · I will introduce Chern's proof of Gauss-Bonnet formula in detail, based on his two papers in the 1940's, and talk about the thoughts hidden in the proof. Chern's … WebMay 25, 1999 · The Gauss-Bonnet formula has several formulations. The simplest one expresses the total Gaussian Curvature of an embedded triangle in terms of the total Geodesic Curvature of the boundary and the Jump Angles at the corners.
