✦ Synopsis


Linial conjectured that Greene-Kleitman's theorem can be extended to general digraphs. We prove a stronger conjecture of Berge for digraphs having k-optimal path partitions consisting of 'long' paths. The same method yields known results for acyclic digraphs, and extensions of various theorems of Greene and Frank to acyclic digraphs.

## Abstract Greene's Theorem states that the maximum cardinality of an optimal __k__‐path in a poset is equal to the minimum __k__‐norm of a __k__‐optimal coloring. This result was extended to all acyclic digraphs, and is conjectured to hold for general digraphs. We prove the result for general dig

In this paper we investigate the foliowing generalization of transitivity: A digraph D is (m, n)-transitive whenever there is a path of length m from x to y there is a subset of n + 1 vertices of these m + 1 vertices which contain a path of length n from x to y. Here we study various properties of

Let D=(V, E) be a digraph with vertex set V of size n and arc set E. For u # V, let d(u) denote the degree of u. A Meyniel set M is a subset of V such that d(u)+d(v) 2n&1 for every pair of nonadjacent vertices u and v belonging to M. In this paper we show that if D is strongly connected, then every
