Rainbow Vertex-Connection and Forbidden Subgraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2018
A path in a vertex-colored graph is called vertex-rainbow if its internal vertices have pairwise distinct colors. A vertex-colored graph G is rainbow vertex-connected if for any two distinct vertices of G, there is a vertex-rainbow path connecting them ...

Rainbow Connection Number of Special Graph and Its Operations [PDF]

open access: yes, 2014
Let $G$ be a simple graph. An edge-coloring of a graph $G$ is rainbow connected if, for any two vertices of $G$, there are $k$ internally vertex-disjoint paths joining them, each of which is rainbow and then a minimal numbers of color $G$ is required to ...

On the rainbow connection numbers of line, middle, and total graphs of wheels

open access: yesElectronic Journal of Graph Theory and Applications
An edge-colored graph G is called rainbow connected if any two vertices in G are connected by a path whose no two edges are colored the same. The rainbow connection of G, denoted by rc(G), is the smallest number of colors needed such that G be a rainbow ...

Rainbow vertex-connection number of 2-connected graphs

open access: yes, 2011
The {\em rainbow vertex-connection number}, $rvc(G)$, of a connected graph $G$ is the minimum number of colors needed to color its vertices such that every pair of vertices is connected by at least one path whose internal vertices have distinct colors. In this paper we first determine the rainbow vertex-connection number of cycle $C_n$ of order $n\geq ...

On the rainbow vertex connection number of general unicyclic graphs

open access: yes
In a graph G, the distance between any two vertices is defined as the length of the shortest path connecting them. A path in G is termed rainbow vertex-connected if all internal vertices along the path have distinct colors.

Rainbow Connection on Amal(Fn,xz,m) Graphs and Amal(On,xz,m) Graphs

open access: yesContemporary Mathematics and Applications (ConMathA)
Coloring graph is giving a color to a set of vertices and a set of edges on a graph. The condition for coloring a graph is that each color is different for each neighboring member graph.
