Veldman, H.J., Cycles containing many vertices of large degree, Discrete Mathematics 101 (1992) 319-325. Let G be a 2-connected graph of order n, r a real number and V, = {u E V(G) ( d(v) 3 r}.
Notions and notations 1.1. Given an undirected graph G let V(G), E(G), K(G) and comp(G) denote the vertex-set, edge-set, vertex connectivity and number of components of G, respectively. Put P(G)={(X, Y): X~V(G), Tc\\_E(G--X)}. For X~V(G) let G(X) denote the induced suL\\*graph. For Y :\\_ E(G) let G
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
