P4-domination in Minimal Imperfect Graphs
نویسنده
چکیده
Numerous studies concerning the number and disposition of chordless paths on four vertices in graphs proved that there is a strong relation between these paths and the perfectness of graphs. In this paper, we further investigate this relation by introducing the notion of P4-domination and formulating two conjectures, which are used both to find an equivalent version of the Odd Pair Conjecture and to frame it. In the last section we prove some particular cases of these conjectures.

On vertex neighborhood in minimal imperfect graphs
Lubiw [11] conjectures that in a minimal imperfect Berge graph, the neighborhood graph N (v) of any vertex v must be connected; this conjecture implies a well known Chvátal’s Conjecture [6] which states that N (v) must contain a P4. In this note we will prove an intermediary conjecture for some classes of minimal imperfect graphs. It is well known that a graph is P4-free if, and only if, every ...
متن کاملOn the domination polynomials of non P4-free graphs
A graph $G$ is called $P_4$-free, if $G$ does not contain an induced subgraph $P_4$. The domination polynomial of a graph $G$ of order $n$ is the polynomial $D(G,x)=sum_{i=1}^{n} d(G,i) x^{i}$, where $d(G,i)$ is the number of dominating sets of $G$ of size $i$. Every root of $D(G,x)$ is called a domination root of $G$. In this paper we state and prove formula for the domination polynomial of no...
متن کاملOn P4-tidy graphs
We study the P4-tidy graphs, a new class defined by Rusu [30] in order to illustrate the notion of P4-domination in perfect graphs. This class strictly contains the P4-extendible graphs and the P4-lite graphs defined by Jamison & Olariu in [19] and [23] and we show that the P4-tidy graphs and P4-lite graphs are closely related. Note that the class of P4-lite graphs is a class of brittle graphs ...
متن کاملUnique domination and domination perfect graphs
We review a characterization of domination perfect graphs in terms of forbidden induced subgraphs obtained by Zverovich and Zverovich [12] using a computer code. Then we apply it to a problem of unique domination in graphs recently proposed by Fischermann and Volkmann. 1 Domination perfect graphs Let G be a graph. A set D ⊆ V (G) is a dominating set of G if each vertex of G either belongs to D ...
متن کاملMinimal separators in P4-sparse graphs
In this paper, we determine the minimal separators of P4-sparse graphs and establish bounds on their number. Specifically, we show that a P4-sparse graph G on n vertices and m edges has fewer than 2n/3 minimal separators of total description size at most 4m/3. The bound on the number of minimal separators is tight and is also tight for the class of cographs, a well known subclass of the P4-spar...
