ACHROMATIC NUMBERS OF MAXIMAL OUTERPLANAR GRAPHS

open access: yesACHROMATIC NUMBERS OF MAXIMAL OUTERPLANAR GRAPHS
application/pdf A complete k-coloring of a graph $G$ is a map from the vertices of $G$ to $k$ colors such that any two adjacent vertices get different colors and that any two different colors appear on the two endpoints of some edge. The achromatic number of $G$ is the largest $k$ such that $G$ has a complete k-coloring.

Total Dominating Sets in Maximal Outerplanar Graphs [PDF]

open access: possibleGraphs and Combinatorics, 2017
A set \(D\subseteq V(G)\) is a total domination set of graph \(G\) if every vertex from \(V(G)\) has a neighbor in \(D\). The minimum cardinality of a total domination set of \(G\) is called total domination number and is denoted by \(\gamma_t(G)\). A recent result from \textit{M. Dorfling} et al. [Discrete Math. 339, No.

Oriented diameter of maximal outerplanar graphs

Journal of Graph Theory, 2021
AbstractLet be a finite connected undirected graph and a strong orientation of . The diameter of , denoted by , is the maximum directed distance between any two vertices of . The oriented diameter of is defined as In this paper, we show that for any maximal outerplanar graph of order , with four exceptions, and the upper bound is sharp.
