## Abstract We investigate the conjecture that a graph is perfect if it admits a two‐edge‐coloring such that two edges receive different colors if they are the nonincident edges of a __P__~4~ (chordless path with four vertices). Partial results on this conjecture are given in this paper. © 1995 Joh

If a graph has q 2 +q+1 vertices (q>13), e edges and no 4-cycles then e 1 2 q(q+1) 2 . Equality holds for graphs obtained from finite projective planes with polarities. This partly answers a question of Erdo s from the 1930's. 1996 Academic Press, Inc. ## 1. Results Let f (n) denote the maximum n
## Abstract The topological approach to the study of infinite graphs of Diestel and KÜhn has enabled several results on Hamilton cycles in finite graphs to be extended to locally finite graphs. We consider the result that the line graph of a finite 4‐edge‐connected graph is hamiltonian. We prove a
We prove the conjecture of Burris and Schelp: a coloring of the edges of a graph of order n such that a vertex is not incident with two edges of the same color and any two vertices are incident with different sets of colors is possible using at most n+1 colors. 1999 Academic Press ## 1. Introducti
