We prove that, with some exceptions, every digraph with n 3 9 vertices and at least ( n -1) ( n -2) + 2 arcs contains all orientations of a Hamiltonian cycle.

We apply proof techniques developed by L. Lovasz and A. Frank to obtain several results on the arc-connectivity of graphs and digraphs. The first results concern the operation of splitting two arcs from a vertex of an Eulerian graph or digraph in such a way as to preserve local connectivity conditio
Greene and Zaslavsky proved that the number of acyclic orientations of a graph G with a unique sink at a given vertex is, up to sign, the linear coefficient of the chromatic polynomial. We give three proofs of this result using pure induction, noncommutative symmetric functions, and an algorithmic b
## Abstract A homomorphism from an oriented graph __G__ to an oriented graph __H__ is a mapping $\varphi$ from the set of vertices of __G__ to the set of vertices of __H__ such that $\buildrel {\longrightarrow}\over {\varphi (u) \varphi (v)}$ is an arc in __H__ whenever $\buildrel {\longrightarrow}
## Abstract A kernel of a directed graph is a set of vertices __K__ that is both absorbant and independent (i.e., every vertex not in __K__ is the origin of an arc whose extremity is in __K__, and no arc of the graph has both endpoints in __K__). In 1983, Meyniel conjectured that any perfect graph,
