Partial Characterizations of Circular-Arc Graphs
نویسندگان
چکیده
A circular-arc graph is the intersection graph of a family of arcs on a circle. A characterization by forbidden induced subgraphs for this class of graphs is not known, and in this work we present a partial result in this direction. We characterize circular-arc graphs by a list of minimal forbidden induced subgraphs when the graph belongs to any of the following classes: P4-free graphs, paw-free graphs, claw-free chordal graphs and diamond-free graphs. c © X John Wiley & Sons, Inc.

Normal Helly circular-arc graphs and its subclasses
A Helly circular-arc modelM = (C,A) is a circle C together with a Helly family A of arcs of C. If no arc is contained in any other, thenM is a proper Helly circular-arc model, if every arc has the same length, then M is a unit Helly circular-arc model, and if there are no two arcs covering the circle, thenM is a normal Helly circular-arc model. A Helly (resp. proper Helly, unit Helly, normal He...
متن کاملCharacterizations and recognition of circular-arc graphs and subclasses: A survey
Circular graphs are intersection graphs of arcs on a circle. These graphs are reported to have been studied since 1964, and they have been receiving considerable attention since a series of papers by Tucker in the 1970s. Various subclasses of circular-arc graphs have also been studied. Among these are the proper circular-arc graphs, unit circular-arc graphs, Helly circular-arc graphs and co-bip...
متن کاملProper Helly Circular-Arc Graphs
A circular-arc model M = (C,A) is a circle C together with a collection A of arcs of C. If no arc is contained in any other then M is a proper circular-arc model, if every arc has the same length then M is a unit circular-arc model and if A satisfies the Helly Property then M is a Helly circular-arc model. A (proper) (unit) (Helly) circular-arc graph is the intersection graph of the arcs of a (...
متن کاملRecognition of circular-arc graphs and some subclasses
In this work we present three new recognition algorithms for circular-arc graphs and for two subclasses of this graph class. We give a linear-time recognition algorithm for circular-arc graphs based on the algorithm of Eschen and Spinrad [ES93, Esc97]. Our algorithm is simpler than the earlier linear-time recognition algorithm of McConnell [McC03], which is the only linear time recognition algo...
متن کاملCharacterizations and Linear Time Recognition of Helly Circular-Arc Graphs
A circular-arc model (C,A) is a circle C together with a collection A of arcs of C. If A satisfies the Helly Property then (C,A) is a Helly circular-arc model. A (Helly) circular-arc graph is the intersection graph of a (Helly) circular-arc model. Circular-arc graphs and their subclasses have been the object of a great deal of attention, in the literature. Linear time recognition algorithm have...
