A directed cycle graph is a directed version of a cycle graph, with all the edges being oriented in the same direction.
In a directed graph, a set of edges which contains at least one edge (or arc) from each directed cycle is called a feedback arc set. Similarly, a set of vertices containing at least one vertex from each directed cycle is called a feedback vertex set.
A directed cycle graph has uniform in-degree 1 and uniform out-degree 1.
Directed cycle graphs are Cayley graphs for cyclic groups (see e.g. Trevisan).
