Comparative Analysis Of Roman And Inverse Roman Domination Numbers Across Graph Families.

Educational Administration: Theory and Practice
This research paper delves into the intriguing realm of Roman domination and its inverse counterpart within various graph structures. Initially defining Roman domination as a graph theory concept where vertices are covered by distinct dominating sets ...

Roman Domination in Graphs

2020
This chapter is concerned with the concept Roman domination in graphs, which was introduced in 2004 by Cockayne, Dreyer, S.M. Hedetniemi, and S.T. Hedetniemi based on the strategies for defending the Roman Empire presented by Stewart (Sci Am 281:136–139, 1999) and ReVelle and Rosing (ReVelle CS, Rosing KE, Am Math Mon 107:585–594, 2000).

Algorithmic Aspects of Outer-Independent Double Roman Domination in Graphs

International Journal of Foundations of Computer Science
Let [Formula: see text] be graph. For any function [Formula: see text], let [Formula: see text], [Formula: see text]. The function [Formula: see text] is called an outer-independent double Roman dominating function (OIDRDF) if the following conditions ...

(Independent) Roman Domination Parameterized by Distance to Cluster

International Conference on Combinatorial Optimization and Applications
Given a graph $G=(V,E)$, a function $f:V\to \{0,1,2\}$ is said to be a \emph{Roman Dominating function} (RDF) if for every $v\in V$ with $f(v)=0$, there exists a vertex $u\in N(v)$ such that $f(u)=2$.

Relations between the Roman k-domination and Roman domination numbers in graphs

Discrete Mathematics, Algorithms and Applications, 2014
Let G = (V, E) be a graph and let k be a positive integer. A Roman k-dominating function ( R k-DF) on G is a function f : V(G) → {0, 1, 2} such that every vertex u for which f(u) = 0 is adjacent to at least k vertices v1, v2, …, vk with f(vi) = 2 for i = 1, 2, …, k.

Roman Domination in Mycielski Graphs: A Study of Some Graphs and a Heuristic Algorithm

Yüzüncü Yıl Üniversitesi Fen Bilimleri Enstitüsü Dergisi
Let G=(V, E) be a graph. A function f: V→\{0,1,2\}, if ∀u for which f(u)=0 is adjacent to ∃v for which f(v)=2, is called a Roman dominating function, and called in short terms RDF. The weight of an RDF f is f(V)=∑\_(v∈V)f(v).

Roman domination in unicyclic graphs [PDF]

open access: possibleJournal of Discrete Mathematical Sciences and Cryptography, 2012
Abstract A Roman dominating function on a graph G = (V, E) is a function f : V → {0, 1, 2} satisfying the condition that every vertex u for which f(u) = 0 is adjacent to at least one vertex v for which f (v) = 2. The weight of a Roman dominating function is the value w (f) = ∑ u∈V f(u).

Roman Domination and Double Roman Domination Numbers of Sierpiński Graphs $$S(K_n,t)$$

Bulletin of the Malaysian Mathematical Sciences Society, 2021
Different types of domination on the Sierpinski graphs $$S(K_n,t)$$ will be studied in this paper. More precisely, we propose a minimal dominating set for each $$S(K_n,t)$$

Roman Jakobson: ‘The Dominant’

1997
The first three stages of Formalist research have been briefly characterized as follows: (1) analysis of the sound aspects of a literary work; (2) problems of meaning within the framework of poetics; (3) integration of sound and meaning into an inseparable whole.
