Abstract: | We generalize an unpublished result of C. Thomassen. Let be a digraph and let be a multiset of subsets of V in such a way that any backward‐infinite path in D meets all the sets . We show that if all is simultaneously reachable from the sets by edge‐disjoint paths, then there exists a system of edge‐disjoint spanning branchings in D where the root‐set of is . |
