A standard problem in combinatorial theory is to characterize structures which satisfy a certain property by providing a minimum list of forbidden substructures, for example, Kuratowski's well known characterization of planar graphs. In this paper, we establish connections between characterization p

It is shown in this note that it can be recognized in polynomial time whether the vertex set of a finite undirected graph can be partitioned into one or two independent sets and one or two cliques. Such graphs generalize bipartite and split graphs and the result also shows that it can be recognized
A blocking system (9, 2Q of a finite set E of objects is two families of non-comparable subsets of E satisfying the non-empty intersection property and the sample set inclusion property. This paper presents nine new examples, and proves 17 U -interchange equality. As applications, bottleneck problem
## Abstract Twelve properties of a highly heterogeneous class of organic solvents have been modeled with a graphβtheoretical molecular connectivity modified (MC) method, which allows to encode the core electrons and the hydrogen atoms. The graphβtheoretical method uses the concepts of simple, gener
