โœฆ Synopsis


We prove the following conjecture of A. Frank (Fifth British Combinatorial Conference, Aberdeen, Scotland, 1975): Let (G) be a connected simple graph of order (n), and (n=n_{1}+\cdots+n_{k}) be a partition of (n) with (n_{i} \geqslant 2). Suppose that the minimum degree of (G) is at least (k). Then the vertex set (V(G)) can be decomposed into disjoint subsets (V_{1}, \ldots, V_{k}) so that (\left|V_{i}\right|=n_{i}) and the subgraph induced by (V_{i}) contains no isolated vertices for all (i, 1 \leqslant i \leqslant k . \quad 1,1995) Academic Press, Inc.

## Abstract The path layer matrix (or path degree sequence) of a graph __G__ contains quantitative information about all possible paths in __G__. The entry (__i,j__) of this matrix is the number of paths in __G__ having initial vertex __i__ and length __j__. It is known that there are cubic graphs
