Cartesian product of graphs have applications in many branches, like coding theory, network designs, chemical graph theory and others. It has been widely studied from different perspectives. For example the L ( 2 , 1 ) labelings of Cartesian products are studied in [11] , [8] . CartesianProduct accepts a sequence of graphs as its arguments and returns the Cartesian product of those graphs. If V1 is the set of vertices of G1, and V2 the set of vertices of G2, then the set of vertices of the Cartesian product G of G1 and G2, is the set V1 X V2.

3-10-2019В В· Cayley graphs are another class of graphs associated with the elements of a group. If this group is associated with some arithmetic function then the Cayley graph becomes an Arithmetic graph. In this paper, we present some results related to basic properties of direct product graphs of Euler totient Cayley graphs with Arithmetic graph. This talk will be accessible to students with just a basic background in graph theory. The speaker will introduce and discuss all advanced topics in the talk. The focus will be on the Alon-Tarsi method, an algebraic tool, for list coloring and its application to Cartesian products of graphs.

We can define the gonality of a graph, like the gonality of a curve, to be the minimum degree of a rank 1 divisor. It turns out that if we know the gonalities of two graphs, then we can find an upper bound on the gonality of the Cartesian product of the two graphs. Hart [8]). Also, Mohar [11] considered the special case of the cartesian product of a graph and a complete graph. In this paper, we consider cartesian products of general graphs. We will establish the relationship between the isoperimetric invariants of graphs and their cartesian products. The
