الملخص الإنجليزي

In 1978 Caccetta and Haggkvist proposed the following conjecture for strict digraphs, which has two forms : the first form is: Let G = (V, E) be a directed graph of order n and girth g such that d + (x) ≥ k for every vertex x.

Then n ≥ K (g-1) + 1.

The second form is : If G is a directed graph with n vertices and if each vertex of G has out degree at least k, then G contains a directed cycle of length at most. Here we investigate two main approaches to prove the conjecture for k ≤ 5 : (1) The first approach is by Hamidoune, which proves the conjecture for k = 3. (2) The second approach is by Hoang and Reed, which proves the conjecture for k ≤ 5.
