Characterizing subclasses of cover-incomparability graphs by forbidden subposets

چکیده
In this paper we demonstrate that several theorems from [1] and [3] do not hold as they are stated. These are the theorems regarding forbidden subposet characterizations of certain classes of coverincomparability graphs. In this paper we correct a mistake in the main theorem of [1], reformulate the corresponding statements and present corrected proofs. We further characterize posets whose cover-incomparability graphs are interval graphs and unit interval graphs.

Characterizing posets for which their natural transit functions coincide
The standard poset transit function of a poset P is a function TP that assigns to a pair of comparable elements the interval between them, while TP (x, y) = {x, y} for a pair x, y of incomparable elements. Posets in which the standard poset transit function coincides with the shortest-path transit function of its cover-incomparability graph are characterized in three ways, in particular with fo...
متن کاملUnit Incomparability Dimension and Clique Cover Width in Graphs
For a clique cover C in the undirected graph G, the clique cover graph of C is the graph obtained by contracting the vertices of each clique in C into a single vertex. The clique cover width of G, denoted by CCW (G), is the minimum value of the bandwidth of all clique cover graphs in G. Any G with CCW (G) = 1 is known to be an incomparability graph, and hence is called, a unit incomparability g...
متن کاملSome new results on circle graphs
Abstract: The intersection graph of a set of chords on a circle is called a circle graph. This class of graphs admits some interesting subclasses, such as: Helly circle graphs, clique-Helly circle graphs, unit circle graphs and proper circular-arc graphs. In this paper, we prove some inclusion relations among these subclasses. A necessary condition for a graph being a Helly circle graph is show...
متن کاملVertex 3-colorability of Claw-free Graphs
The 3-colorability problem is NP-complete in the class of clawfree graphs and it remains hard in many of its subclasses obtained by forbidding additional subgraphs. (Line graphs and claw-free graphs of vertex degree at most four provide two examples.) In this paper we study the computational complexity of the 3-colorability problem in subclasses of claw-free graphs defined by finitely many forb...
متن کاملColouring vertices of triangle-free graphs without forests
The vertex colouring problem is known to be NP-complete in the class of triangle-free graphs. Moreover, it is NP-complete in any subclass of triangle-free graphs defined by a finite collection of forbidden induced subgraphs, each of which contains a cycle. In this paper, we study the vertex colouring problem in subclasses of triangle-free graphs obtained by forbidding graphs without cycles, i.e...
