A sub-Riemannian Gauss-Bonnet theorem for surfaces in contact manifolds

Journal of Geometric Analysis, 2022
We obtain a sub-Riemannian version of the classical Gauss-Bonnet theorem. We consider subsurfaces of three-dimensional contact sub-Riemannian manifolds. Using a family of taming Riemannian metrics on the surface which approach a sub-Riemannian metric, we

Topological Origin of Horizon Temperature via the Chern–Gauss–Bonnet Theorem

JETP Letters : Journal of Experimental And Theoretical Physics Letters
This paper establishes a connection between the Hawking temperature of spacetime horizons and global topological invariants, specifically the Euler characteristic of Wick-rotated Euclidean spacetimes.

The Gauss–Bonnet theorem

Columbia Journal of Undergraduate Mathematics
The Gauss–Bonnet theorem is a crowning result of surface theory that gives a fundamental connection between geometry and topology. Roughly speaking, geometry refers to the “local” properties—lengths, angles, curvature— of some fixed object, while ...
