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

Determining the Locating Rainbow Connection Number of Vertex-Transitive Graphs
The locating rainbow connection number of a graph is defined as the minimum number of colors required to color vertices such that every two vertices there exists a rainbow vertex path and every vertex has a distinct rainbow code.

The Rainbow Vertex Connection Number of Some Amalgamation of Two Cycles
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.

Rainbow Vertex-Connection Number [PDF]
All the above parameters on rainbow connections involved edge-colorings of graphs. A natural idea is to introduce a similar parameter involving vertex-colorings of graphs. It is, as mentioned above, a vertex version of the rainbow connection number. Krivelevich and Yuster (J.

The rainbow connection problem: Mathematical formulations
The concept of rainbow connection was introduced by Chartrand et al. in 2008. The rainbow connection number, rc(G), of a connected graph G = (V, E) is the minimum number of colors needed to color the edges of E, so that each pair of the vertices in V is ...

The rainbow vertex connection number of star wheel graphs [PDF]
A vertex-colored graph G = (V(G), E(G)) is said to be rainbow vertex-connected, if for every two vertices u and v in V(G), there exists a u – v path with all internal vertices have distinct colors. The rainbow vertex connection number of G, denoted by rvc(G), is the smallest number of colors needed to make G rainbow vertex connected.
