The Planar Index and Outerplanar Index of Some Graphs Associated to Commutative Rings

Discussiones Mathematicae - General Algebra and Applications, 2019
In this paper, we study the planar and outerplanar indices of some graphs associated to a commutative ring. We give a full characterization of these graphs with respect to their planar and outerplanar indices when R is a finite ring.

The Subset-Strong Product of Graphs

Annales Mathematicae Silesianae
In this paper, we introduce the subset-strong product of graphs and give a method for calculating the adjacency spectrum of this product. In addition, exact expressions for the first and second Zagreb indices of the subset-strong products of two graphs ...

On the distinguishing chromatic number of the Kronecker products of graphs

AKCE International Journal of Graphs and Combinatorics
In this paper, we investigate the distinguishing chromatic number of Kronecker product of paths, cycles, star graphs, symmetric trees, almost symmetric trees, and bisymmetric trees.
