## Abstract It is shown that every 4βchromatic graph on __n__ vertices contains an odd cycle of length less than $2\sqrt {n}\,+3$. This improves the previous bound given by Nilli [J Graph Theory 3 (1999), 145β147]. Β© 2001 John Wiley & Sons, Inc. J Graph Theory 37: 115β117, 2001
## Abstract For a graph __G__, we denote by __d__~__G__~(__x__) and ΞΊ(__G__) the degree of a vertex __x__ in __G__ and the connectivity of __G__, respectively. In this article, we show that if __G__ is a 3βconnected graph of order __n__ such that __d__~__G__~(__x__) + __d__~__G__~(__y__) + __d__~__
Chen, C. and J. Wang, Factors in graphs with odd-cycle property, Discrete Mathematics 112 (1993) 29-40. We present some conditions for the existence of a (g,f)-factor or a (g,f)-parity factor in a graph G with the odd-cycle property that any two odd cycles of G either have a vertex in common or are
