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

We show that the minimum set of unordered graphs that must be forbidden to get the same graph class characterized by forbidding a single ordered graph is infinite.
## Abstract Let __T__ be the line graph of the unique tree __F__ on 8 vertices with degree sequence (3,3,3,1,1,1,1,1), i.e., __T__ is a chain of three triangles. We show that every 4‐connected {__T__, __K__~1,3~}‐free graph has a hamiltonian cycle. © 2005 Wiley Periodicals, Inc. J Graph Theory 49:
## Abstract Let ${\cal C}$ be a family of __n__ compact connected sets in the plane, whose intersection graph $G({\cal C})$ has no complete bipartite subgraph with __k__ vertices in each of its classes. Then $G({\cal C})$ has at most __n__ times a polylogarithmic number of edges, where the exponent
## Abstract A path graph is the intersection graph of subpaths of a tree. In 1970, Renz asked for a characterization of path graphs by forbidden induced subgraphs. We answer this question by determining the complete list of graphs that are not path graphs and are minimal with this property. © 2009
## Abstract Given a set ${\cal F}$ of graphs, a graph __G__ is ${\cal F}$‐free if __G__ does not contain any member of ${\cal F}$ as an induced subgraph. We say that ${\cal F}$ is a degree‐sequence‐forcing set if, for each graph __G__ in the class ${\cal C}$ of ${\cal F}$‐free graphs, every realiza
