Let H be a digraph possibly with loops and D a digraph (possibly infinite) without loops whose arcs are coloured with the vertices of H (D is an H-coloured digraph). V(D) and A(D) will denote the sets of vertices and arcs of D respectively. A directed walk or a directed pathW in D is an H-walk or an H-path if and only if the consecutive colors encountered onW form a directed walk in H. A set N ...
