A theorem of J. Edmonds states that a directed graph has k edge-disjoint branchings rooted at a vertex r if and only if every vertex has k edge-disjoint paths to r . We conjecture an extension of this theorem to vertex-disjoint paths and give a constructive proof of the conjecture in the case k = 2.

Let G be a simple graph with n vertices and let G c denote the complement of G . Let ( G ) denote the number of components of G and G ( E ) the spanning subgraph of G with edge set E . where the minimum is taken over all such partitions . In [ Europ . J . Combin . 7 (1986) , 263 -270] , Payan conj
## Abstract We give a sufficient condition for a simple graph __G__ to have __k__ pairwise edgeβdisjoint cycles, each of which contains a prescribed set __W__ of vertices. The condition is that the induced subgraph __G__[__W__] be 2__k__βconnected, and that for any two vertices at distance two in _
## Abstract We introduce a method for reducing __k__βtournament problems, for __k__ββ₯β3, to ordinary tournaments, that is, 2βtournaments. It is applied to show that a __k__βtournament on __n__ββ₯βkβ+β1β+β24__d__ vertices (when __k__ββ₯β4) or on __n__ββ₯β30__d__β+β2 vertices (when __k__β=β3) has __d__
