Abstract

A travel groupoid is an algebraic system related to graphs, which was defined by Nebeský in 2006. In this article, we characterize simple non-confusing travel groupoids on a finite graph in two ways. One is given by using spanning trees of the graph and the other by its subgroupoids. Furthermore, we introduce a way to construct a simple non-confusing travel groupoid on a given finite graph by using the spanning trees, and we count numbers of simple non-confusing travel groupoids on cycle graphs and cactus graphs.
