| Abstract: | Directed pathwidth is a natural generalization of pathwidth to digraphs. It is well-known that undirected graphs of pathwidth at most one are characterized by two forbidden minors [BFKL87]. In this paper, we show that the digraphs of directed pathwidth at most one are characterized by a finite number of directed minors. |
