Graphs on surfaces with positive Forman curvature or corner curvature

Combinatorics 2020-02-11 v1 Differential Geometry

Abstract

On one hand, we study the class of graphs on surfaces, satisfying tessellation properties, with positive Forman curvature on each edge. Via medial graphs, we provide a new proof for the finiteness of the class, and give a complete classification. On the other hand, we classify the class of graphs on surfaces with positive corner curvature.
