Rotation systems and simple drawings in surfaces

Geometric Topology 2022-07-04 v1 Combinatorics

Abstract

Every simple drawing of a graph in the plane naturally induces a rotation system, but it is easy to exhibit a rotation system that does not arise from a simple drawing in the plane. We extend this to all surfaces: for every fixed surface Σ\Sigma, there is a rotation system that does not arise from a simple drawing in Σ\Sigma.
