A generalization of a recent result of Tomescu ( 1993) is presented. The method is purely combinatorial and is based on the theory of species of several variables.

✦ Synopsis
A (D, c)-coloring of the complete graph K" is a coloring of the edges with c colors such that all monochromatic connected subgraphs have at most D vertices. Resolvable block designs with c parallel classes and with block size D are natural examples of (D, c)-colorings. However, (D, c)-colorings are more relaxed structures.
We investigate the largest n such that K" has a (D, c)-coloring.
Our main tool is the fractional matching theory of hypergraphs.

The tree partition number of an r-edge-colored graph G, denoted by t r (G), is the minimum number k such that whenever the edges of G are colored with r colors, the vertices of G can be covered by at most k vertex-disjoint monochromatic trees. We determine t 2 (K (n 1 ; n 2 ; . . . ; n k )) of the c
For every positive integer r there exists a constant C r depending only on r such that for every colouring of the edges of the complete bipartite graph K n, n with r colours, there exists a set of at most C r monochromatic cycles whose vertex sets partition the vertex set of K n, n . This answers a
An edge dominating set in a graph G is a set of edges D such that every edge not in D is adjacent to an edge of D. An edge domatic partition of a graph C=(V, E) is a collection of pairwise-disjoint edge dominating sets of G whose union is E. The maximum size of an edge domatic partition of G is call
