Criticality indices of 2-rainbow domination of paths and cycles [PDF]

open access: yesOpuscula Mathematica, 2016
A \(2\)-rainbow dominating function of a graph \(G\left(V(G),E(G)\right)\) is a function \(f\) that assigns to each vertex a set of colors chosen from the set \(\{1,2\}\) so that for each vertex with \(f(v)=\emptyset\) we have \({\textstyle\bigcup_{u\in ...

Characterization of signed paths and cycles admitting minus dominating function [PDF]

open access: yesCommunications in Combinatorics and Optimization, 2020
Let $G=(V,E,\sigma)$ be a finite signed graph. A function $f: V \rightarrow\{-1,0,1\}$ is a minus dominating function (MDF) of $ G $ if $f(u)+\sum_{v \in N(u)} \sigma (uv)f(v)\geq 1 $ for all $ u\in V $. In this paper we characterize signed paths and

Connected domination game played on Cartesian products

open access: yesOpen Mathematics, 2019
The connected domination game on a graph G is played by Dominator and Staller according to the rules of the standard domination game with the additional requirement that at each stage of the game the selected vertices induce a connected subgraph of G. If

Decomposition of hypercube graphs into paths and cycles of length four

open access: yesAKCE International Journal of Graphs and Combinatorics, 2022
By a [Formula: see text]-decomposition of a graph G, we mean a partition of the edge set of G into p paths of length 4 and q cycles of length 4. In this paper, we give conditions for a [Formula: see text]-decomposition of the n-dimensional hypercube ...

Paths and cycles in colored graphs [PDF]

open access: yes, 2001
Let G be an (edge-)colored graph. A path (cycle) is called monochromatic if all the edges of it have the same color, and is called heterochromatic if all the edges of it have different colors. In this note, some sufficient conditions for the existence of

Cycles and transitivity by monochromatic paths in arc-coloured digraphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2015
A digraph D is an m-coloured digraph if its arcs are coloured with m colours. If D is an m-coloured digraph and a∈A(D), then colour(a) will denote the colour has been used on a.

On the radio number for corona of paths and cycles

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
Radio -coloring of graphs is one of the variations of frequency assignment problem. For a simple connected graph and a positive integer , a radio -coloring is an assignment of positive integers (colors) to the vertices of such that for every pair of ...
