On subset labelings of trees

AKCE International Journal of Graphs and Combinatorics
For a nontrivial graph G, a subset labeling of G is a labeling of the vertices of G with nonempty subsets of the set [Formula: see text] for a positive integer r such that two vertices of G have disjoint labels if and only if the vertices are adjacent ...

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 ...
