Rainbow Vertex-Connection and Forbidden Subgraphs

Discussiones 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 ...

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

Electronic 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

, 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 ...

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

Contemporary 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.
