## 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
## Abstract The edge‐toughness __T__~1~(__G__) of a graph __G__ is defined as equation image where the minimum is taken over every edge‐cutset __X__ that separates __G__ into ω (__G__ ‐ __X__) components. We determine this quantity for some special classes of graphs that also gives the arboricity
