We show that the edges of a 2-connected graph can be partitioned into two color classes so that every vertex is incident with edges of each color and every alternating cycle passes through a single edge. We also show that the edges of a simple graph with minimum vertex degree 6 2 2 can be partitione

Abstract
Sufficient degree conditions for the existence of properly edgeβcolored cycles and paths in edgeβcolored graphs, multigraphs and random graphs are investigated. In particular, we prove that an edgeβcolored multigraph of order n on at least three colors and with minimum colored degree greater than or equal to β(n+1)/2β has properly edgeβcolored cycles of all possible lengths, including hamiltonian cycles. Longest properly edgeβcolored paths and hamiltonian paths between given vertices are considered as well. Β© 2009 Wiley Periodicals, Inc. J Graph Theory 64: 63β86, 2010

It is shown that, for β ) 0 and n ) n β , any complete graph K on n vertices 0 ' Ε½ . whose edges are colored so that no vertex is incident with more than 1 y 1r 2 y β n edges of the same color contains a Hamilton cycle in which adjacent edges have distinct colors. Moreover, for every k between 3 and
## Abstract An edgeβcolored graph __H__ is properly colored if no two adjacent edges of __H__ have the same color. In 1997, J. BangβJensen and G. Gutin conjectured that an edgeβcolored complete graph __G__ has a properly colored Hamilton path if and only if __G__ has a spanning subgraph consisting
## Abstract Let __G__ be a simple graph of order __n__ and minimal degree >βcn (0β<βcβ<β1/2). We prove that (1) There exist __n__~0~β=β__n__~0~(__c__) and __k__β=β__k__(__c__) such that if __n__β>β__n__~0~ and __G__ contains a cycle __C__~__t__~ for some __t__β>β2__k__, then __G__ contains a cycle
Let G be a graph of order n satisfying d(u) + d(v) β₯ n for every edge uv of G. We show that the circumference-the length of a longest cycle-of G can be expressed in terms of a certain graph parameter, and can be computed in polynomial time. Moreover, we show that G contains cycles of every length be
## Abstract Let __G__ be a graph of order __n__ and define __NC(G)__ = min{|__N__(__u__) βͺ __N__(__v__)| |__uv__ β __E__(__G__)}. A cycle __C__ of __G__ is called a __dominating cycle__ or __D__β__cycle__ if __V__(__G__) β __V__(__C__) is an independent set. A __D__β__path__ is defined analogously.
