The purpose of this paper is to give a necessary and sufficient condition for a digraph G to contain k arcdisjoint arborescences so that the number rooted at each vertex x of G lies in some prescribed interval which depends on x. A digraph G = (V, E) consists of a vertex set V and an arc set E such
## Abstract A natural digraph analog of the graph theoretic concept of βan independent setβ is that of βan acyclic set of vertices,β namely a set not spanning a directed cycle. By this token, an analog of the notion of coloring of a graph is that of decomposition of a digraph into acyclic sets. We
