## Abstract We study classes of finite, simple, undirected graphs that are (1) lower ideals (or hereditary) in the partial order of graphs by the induced subgraph relation β€~i~, and (2) wellβquasiβordered (WQO) by this relation. The main result shows that the class of cographs (__P~4~__βfree graphs

β¦ Synopsis
Let G and K be connected graphs such that I GI = nlKl (n 2 2) and let p be a fixed integer satisfying 1 < p < n. We prove that if G \ A has a K-factor for every connected subgraph A with IAl = plKI, then G also has a K-factor.

Beineke and Robertson independently characterized line graphs in terms of nine forbidden induced subgraphs. In 1994, S8 olte s gave another characterization, which reduces the number of forbidden induced subgraphs to seven, with only five exceptional cases. A graph is said to be a dumbbell if it con
## Abstract A subgraph of a graph __G__ is called __trivial__ if it is either a clique or an independent set. Let __q(G)__ denote the maximum number of vertices in a trivial subgraph of __G__. Motivated by an open problem of ErdΕs and McKay we show that every graph __G__ on __n__ vertices for which
We study bipartite graphs partially ordered by the induced subgraph relation. Our goal is to distinguish classes of bipartite graphs that are or are not well-quasi-ordered (wqo) by this relation. Answering an open question from [J Graph Theory 16 (1992), 489-502], we prove that P 7 -free bipartite g
If G is a block, then a vertex u of G is called critical if Gu is not a block. In this article, relationships between the localization of critical vertices and the localization of vertices of relatively small degrees (especially, of degree two) are studied. A block is called semicritical if a) each
## Abstract In this paper, we consider forbidden subgraphs which force the existence of a 2βfactor. Let \documentclass{article}\footskip=0pc\pagestyle{empty}\begin{document}${\cal G}$\end{document} be the class of connected graphs of minimum degree at least two and maximum degree at least three, an
