On the Rainbow Vertex-Connection

open access: yesDiscussiones Mathematicae Graph Theory, 2013
A vertex-colored graph is rainbow vertex-connected if any two vertices are connected by a path whose internal vertices have distinct colors. The rainbow vertex-connection of a connected graph G, denoted by rvc(G), is the smallest number of colors that ...

The complexity of determining the rainbow vertex-connection of a graph

open access: yesTheoretical Computer Science, 2011
A vertex-colored graph is rainbow vertex-connected if any two vertices are connected by a path whose internal vertices have distinct colors, which was introduced by Krivelevich and Yuster.

Rainbow connection number of amalgamation of some graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2016
Let G be a nontrivial connected graph. For k∈N, we define a coloring c:E(G)→{1,2,…,k} of the edges of G such that adjacent edges can be colored the same. A path P in G is a rainbow path if no two edges of P are colored the same. A rainbow path connecting

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

Bilangan Terhubung Titik Pelangi pada Graf Hasil Operasi Korona Graf Prisma (P_(m,2)) dan Graf Lintasan (P_3)

open access: yesJambura Journal of Mathematics, 2022
Rainbow vertex-connection number is the minimum k-coloring on the vertex graph G and is denoted by rvc(G). Besides, the rainbow-vertex connection number can be applied to some special graphs, such as prism graph and path graph.
