Vines and MAT-labeled graphs

Forum of Mathematics, Sigma
The present paper explores a connection between two concepts arising from different fields of mathematics. The first concept, called vine, is a graphical model for dependent random variables.

Optimal L(3,2,1)-labeling of trees

AKCE International Journal of Graphs and Combinatorics
Given a graph G, an [Formula: see text]-labeling of G is an assignment f of non-negative integers (labels) to the vertices of G such that [Formula: see text] if [Formula: see text] (i = 1, 2, 3).

On the Beta-Number of Forests with Isomorphic Components

Discussiones Mathematicae Graph Theory, 2018
The beta-number, β (G), of a graph G is defined to be either the smallest positive integer n for which there exists an injective function f : V (G) → {0, 1, . . .

A-vertex magicness of product of graphs

AKCE International Journal of Graphs and Combinatorics
In this paper, we discuss the A-vertex magicness of some products of graphs, where A is a non-trivial additive Abelian group with identity 0. We characterize A-vertex magicness of the Cartesian product of Pn and Pm, where A has at least three elements ...
