WebGauss-Bonnet is a deep result in di erential geometry that illus-trates a fundamental relationship between the curvature of a surface and its Euler characteristic. In this paper I introduce and examine properties of dis-crete surfaces in e ort to prove a discrete Gauss-Bonnet analog. I preface this 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 of triangles containing the vertex v. Then 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 … See more The theorem applies in particular to compact surfaces without boundary, in which case the integral See more A number of earlier results in spherical geometry and hyperbolic geometry, discovered over the preceding centuries, were subsumed as special cases of Gauss–Bonnet. Triangles In See more The Chern theorem (after Shiing-Shen Chern 1945) is the 2n-dimensional generalization of GB (also see Chern–Weil homomorphism See more

WebNov 21, 2011 · In this paper, we give four different proofs of the Gauss-Bonnet-Chern theorem on Riemannian manifolds, namely Chern's simple intrinsic proof, a topological proof, Mathai-Quillen's Thom form proof and McKean-Singer-Patodi's heat equation proof. Web1.7 The Gauss-Bonnet theorem. The Gauss-Bonnet theorem is a profound theorem of differential geometry, linking global and local geometry. Consider a surface patch R, bounded by a set of m curves ξi. If the edges ξi meet at exterior angles θi and they have geodesic curvature κg ( si) where si labels a point on ξi then the theorem says.
