Dominating induced matchings and other graph parameters

open access: yesAKCE International Journal of Graphs and Combinatorics
A matching M in a graph G is an induced matching if the largest degree of the subgraph of G induced by M is equal to one. A dominating induced matching (DIM) of G is an induced matching that dominates every edge of G. It is well known that, if they exist,

Dominating Induced Matchings in $S_{1,2,4}$-Free Graphs [PDF]

open access: yesDiscrete Applied Mathematics, 2017
Let $G=(V,E)$ be a finite undirected graph without loops and multiple edges. A subset $M \subseteq E$ of edges is a {\em dominating induced matching} ({\em d.i.m.}) in $G$ if every edge in $E$ is intersected by exactly one edge of $M$. In particular, this means that $M$ is an induced matching, and every edge not in $M$ shares exactly one vertex with an

Some Results on Dominating Induced Matchings

open access: yesGraphs and Combinatorics, 2022
Let $G$ be a graph, a dominating induced matching (DIM) of $G$ is an induced matching that dominates every edge of $G$. In this paper we show that if a graph $G$ has a DIM, then $ (G) \leqslant 3$. Also, it is shown that if $G$ is a connected graph whose all edges can be partitioned into DIM, then $G$ is either a regular graph or a biregular graph and

Dominating Induced Matchings for P 7-free Graphs in Linear Time [PDF]

open access: yesAlgorithmica, 2011
Let $G$ be a finite undirected graph with edge set $E$. An edge set $E' \subseteq E$ is an {\em induced matching} in $G$ if the pairwise distance of the edges of $E'$ in $G$ is at least two; $E'$ is {\em dominating} in $G$ if every edge $e \in E \setminus E'$ intersects some edge in $E'$.

Paired and induced-paired domination in (E,net)-free graphs [PDF]

open access: yes, 2011
A dominating set of a graph is a vertex subset that any vertex belongs to or is adjacent to. Among the many well-studied variants of domination are the so-called paired-dominating sets.

More Applications of the d-Neighbor Equivalence: Connectivity and Acyclicity Constraints [PDF]

open access: yes, 2019
In this paper, we design a framework to obtain efficient algorithms for several problems with a global constraint (acyclicity or connectivity) such as Connected Dominating Set, Node Weighted Steiner Tree, Maximum Induced Tree, Longest Induced Path, and ...

The Maximum Number of Dominating Induced Matchings

open access: yesJournal of Graph Theory, 2014
AbstractA matching M of a graph G is a dominating induced matching (DIM) of G if every edge of G is either in M or adjacent with exactly one edge in M. We prove sharp upper bounds on the number of DIMs of a graph G and characterize all extremal graphs.

Dominating induced matchings in graphs containing no long claw [PDF]

open access: yesJournal of Graph Theory, 2017
AbstractAn induced matching M in a graph G is dominating if every edge not in M shares exactly one vertex with an edge in M. The dominating induced matching problem (also known as efficient edge domination) asks whether a graph G contains a dominating induced matching.

Efficient and Perfect domination on circular-arc graphs [PDF]

open access: yes, 2015
Given a graph $G = (V,E)$, a \emph{perfect dominating set} is a subset of vertices $V' \subseteq V(G)$ such that each vertex $v \in V(G)\setminus V'$ is dominated by exactly one vertex $v' \in V'$.
