Impulse Gauss Curvatures [PDF]

open access: yes, 2004
In Riemannian (differential) geometry, the differences between Euclidean geometry, elliptic geometry, and hyperbolic geometry are understood in terms of curvature. I think Gauss and Riemann captured the essence of geometry in their studies of surfaces and manifolds, and their point of view is spectacularly illuminating.

The Gauss Map of Complete Minimal Surfaces with Finite Total Curvature

open access: yesAnais da Academia Brasileira de Ciências, 2013
In this paper we are concerned with the image of the normal Gauss map of a minimal surface immersed in ℝ3 with finite total curvature. We give a different proof of the following theorem of R.

Flow by powers of the Gauss curvature [PDF]

open access: yesAdvances in Mathematics, 2016
The authors prove that convex hypersurfaces in \(\mathbb{R}^{n+1}\) contracting under the flow by any power \(\alpha>\frac{1}{n+2}\) of the Gauss curvature converge after rescaling to fixed volume to a limit which is a smooth uniformly self-similar contracting solution of the flow.

Quadratic curvature corrections to stringy effective actions and the absence of de Sitter vacua

open access: yesJournal of High Energy Physics, 2022
We investigate the combined effect of fluxes and higher-order curvature corrections, in the form of the Gauss-Bonnet term, on the existence of de Sitter vacua in a heterotic string inspired framework, compactified on spheres and tori.

Surfaces Moving by Powers of Gauss Curvature [PDF]

open access: yesPure and Applied Mathematics Quarterly, 2012
We prove that strictly convex surfaces moving by $K^{α/2}$ become spherical as they contract to points, provided $α$ lies in the range $[1,2]$. In the process we provide a natural candidate for a curvature pinching quantity for surfaces moving by arbitrary functions of curvature, by finding a quantity conserved by the reaction terms in the evolution of

Approximation of Gaussian Curvature by the Angular Defect: An Error Analysis

open access: yesMathematical and Computational Applications, 2021
It is common practice in science and engineering to approximate smooth surfaces and their geometric properties by using triangle meshes with vertices on the surface.

Analytical study of holographic p-wave superfluid models in Gauss–Bonnet gravity

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
In Gauss–Bonnet gravity, we analytically investigate the p-wave superfluid models in five dimensional AdS soliton and AdS black hole in order to explore the influences of the higher curvature correction on the holographic superfluid phase transition.

Analytical study of holographic superconductor with backreaction in 4d Gauss-Bonnet gravity

open access: yesPhysics Letters B, 2021
In this paper we have analytically investigated holographic superconductors in four dimensional Einstein-Gauss-Bonnet gravity background. Recently the novel four dimensional Einstein-Gauss-Bonnet gravity has been formulated by rescaling the Gauss-Bonnet ...

Submanifolds with curvature normals of constant length and the Gauss map [PDF]

open access: yes, 2004
We show that a submanifold with curvature normal of constant length has constant principal curvatures under suitable global hypothesis.
