This web page contains the abstract of my paper:

"A Property of the Colored Complete Graph", Discrete Mathematics, 25(1979), p. 175-178.

Abstract: If the lines of the complete graph Kn are colored so that no point is on more than (n-1)/7 lines of the same color or so that each point lies on more than (5*n+8)/7 lines of different colors, then Kn contains a cycle of length n with adjacent lines having different colors.
