Rainbow connections of bioriented graphs. [PDF]

open access: yesHeliyon, 2023
For a directed graph D, it's deemed rainbow connected if each arc is assigned a different color, so that all paths from the vertex u to the vertex v are rainbow connected. Rainbow connection number refers to how many colors are needed in D to achieve rainbow connectivity.

Strong rainbow connection in digraphs

open access: yesDiscrete Applied Mathematics, 2018
International audienceAn arc-coloured digraph is strongly rainbow connected if for every pair of vertices (u, v) there exists a shortest path from u to v all of whose arcs have different colours.

Proper Rainbow Connection Number of Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2021
A path in an edge-coloured graph is called a rainbow path if its edges receive pairwise distinct colours. An edge-coloured graph is said to be rainbow connected if any two distinct vertices of the graph are connected by a rainbow path.

Rainbow Connection In Sparse Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2013
An edge-coloured connected graph $G = (V,E)$ is called rainbow-connected if each pair of distinct vertices of $G$ is connected by a path whose edges have distinct colours.

Rainbow connection in graphs [PDF]

open access: yesMathematica Bohemica, 2008
summary:Let $G$ be a nontrivial connected graph on which is defined a coloring $c\: E(G) \rightarrow \lbrace 1, 2, \ldots , k\rbrace $, $k \in {\mathbb{N}}$, of the edges of $G$, where adjacent edges may be colored the same.

Rainbow Connection in 3-Connected Graphs [PDF]

open access: yesGraphs and Combinatorics, 2012
An edge-colored graph $G$ is rainbow connected if any two vertices are connected by a path whose edges have distinct colors. The rainbow connection number of a connected graph $G$, denoted by $rc(G)$, is the smallest number of colors that are needed in order to make $G$ rainbow connected.

Total rainbow connection of digraphs

open access: yesDiscrete Applied Mathematics, 2018
An edge-coloured path is rainbow if its edges have distinct colours. For a connected graph $G$, the rainbow connection number (resp. strong rainbow connection number) of $G$ is the minimum number of colours required to colour the edges of $G$ so that, any two vertices of $G$ are connected by a rainbow path (resp. rainbow geodesic).
