A characterization of 2-tree proper interval 3-graphs

HIGHLIGHTS

• who: David E. Brown from the Department of Mathematics and Statistics, Utah State University, Logan, UT, USA have published the research work: A Characterization of 2-Tree Proper Interval 3-Graphs, in the Journal: (JOURNAL) of 23/02/2014
• what: The authors characterize the class of 2-trees which are interval 3-graphs via a list of three graphs and three infinite families of forbidden induced subgraphs. What structure this is is not easily named; indeed it is in a sense the purpose of this paper to investigate what prohibits an interval 3-graph from . . .
