Let the trunk of a graph G be the graph obtained by removing all leaves of G. We prove that, for every integer c \_> 2, there are at most finitely many trunks of serniharrnonic graphs with cyclomatic number e--in contrast to the fact established by the last two of the present authors in their paper

Let P(n) be the class of all connected graphs having exactly n ~> 1 negative eigenvalues (including their multiplicities). In this paper we prove that the class P(n) contains only finitely many so-called canonical graphs. The analogous statement for the class Q(n) of all connected graphs having exac
Let G be a simple graph of order n(G). A vertex set D of G is dominating if every vertex not in D is adjacent to some vertex in D, and D is a covering if every edge of G has at least one end in D. The domination number 7(G) is the minimum order of a dominating set, and the covering number/~(G) is th
## Abstract A wellโcovered graph is a graph in which every maximal independent set is a maximum independent set; Plummer introduced the concept in a 1970 paper. The notion of a 1โwellโcovered graph was introduced by Staples in her 1975 dissertation: a wellโcovered graph __G__ is 1โwellโcovered if a
Following [1] , we investigate the problem of covering a graph G with induced subgraphs G 1 ; . . . ; G k of possibly smaller chromatic number, but such that for every vertex u of G, the sum of reciprocals of the chromatic numbers of the G i 's containing u is at least 1. The existence of such ''ch
## Abstract This note contains an example of a 4โchromatic graph which admits a vertex partition into three parts such that the union of every two of them induces a forest. ยฉ 2001 John Wiley & Sons, Inc. J Graph Theory 37: 243โ246, 2001
