Simple $k$-Planar Graphs are Simple $(k+1)$-Quasiplanar

Abstract

A simple topological graph is $k$-quasiplanar ($k\ge 2$) if it contains no $k$ pairwise crossing edges, and $k$-planar if no edge is crossed more than $k$ times. In this paper, we explore the relationship between $k$-planarity and $k$-quasiplanarity to show that, for $k\ge 2$, every $k$-planar simple topological graph can be transformed into a $(k+1)$-quasiplanar simple topological graph.
