RAINBOW VERTEX CONNECTION NUMBER OF BULL GRAPH, NET GRAPH, TRIANGULAR LADDER GRAPH, AND COMPOSITION GRAPH (P_n [P_1 ]) [PDF]

open access: yesBarekeng
The rainbow connection was first introduced by Chartrand in 2006 and then in 2009 Krivelevich and Yuster first time introduced the rainbow vertex connection. Let graph be a connected graph.

The Vertex-Rainbow Connection Number of Some Graph Operations [PDF]

open access: yesDiscussiones Mathematicae Graph Theory, 2021
A path in an edge-colored (respectively vertex-colored) graph G is rainbow (respectively vertex-rainbow) if no two edges (respectively internal vertices) of the path are colored the same.

Further hardness results on the rainbow vertex-connection number of graphs

open access: yesTheoretical Computer Science, 2013
A vertex-colored graph $G$ is {\it rainbow vertex-connected} if any pair of vertices in $G$ are connected by a path whose internal vertices have distinct colors, which was introduced by Krivelevich and Yuster. The {\it rainbow vertex-connection number} of a connected graph $G$, denoted by $rvc(G)$, is the smallest number of colors that are needed in ...

A Study on Strong Rainbow Vertex-Connection in Some Classes of Generalized Petersen Graphs

open access: yesProcedia Computer Science, 2020
Abstract In a vertex colored graph G, a rainbow path is defined as a path in which all the internal vertices get different colors. The graph G is called a strongly rainbow vertex-connected graph, if at least one shortest rainbow path exists between every pair of distinct vertices. The strong rainbow vertex-connection number, represented by srvc(G) is

The Rainbow Vertex Connection Number of Some Amalgamation of Two Cycles

open access: yesTensor: Pure and Applied Mathematics Journal
This paper focuses on rainbow vertex coloring in a graph G, in which, for every two vertices in G, there exists a rainbow vertex path where all internal vertices have distinct colors. The rainbow vertex connection number of G, denoted by rvc(G), is the minimum number of colors required to make G rainbow-vertex connected. In this paper, we determine the
