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

β¦ Synopsis
We prove that if the edges of the complete graph on n ~4 vertices are colored so that no vertex is on more than A edges of the same color, 1 c A < n -2,, then the graph has cycles of all lengths 3 through n with no A consecutive edges the same color.

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 We give necessary and sufficient conditions for the existence of an alternating Hamiltonian cycle in a complete bipartite graph whose edge set is colored with two colors.
We prove an asymptotic existence theorem for decompositions of edge-colored complete graphs into prespecified edge-colored subgraphs. Many combinatorial design problems fall within this framework. Applications of our main theorem require calculations involving the numbers of edges of each color 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 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 degre
