The tripartite-circle crossing number of graphs with two small partition classes
Charles Camacho, Silvia Fernández-Merchant, Marija Jelić Milutinović +4
A tripartite-circle drawing of a tripartite graph is a drawing in the plane, where each part of a vertex partition is placed on one of three disjoint circles, and the edges do not…

Counting the Number of Quasiplatonic Topological Actions of the Cyclic Group on Surfaces
Charles Camacho
Define to be the number of quasiplatonic topological actions of the cyclic group on surfaces of genus at least two. We use formulas of Benim and Wootton to give an ex…
