Abstract

We consider a proper total coloring \( \sigma \) of edges and vertices in a simple graph \( G \) and the sum \( f(v) \) of colors of all the edges incident to \( v \) and the color of a vertex \( v \). We say that a coloring \( \sigma \) is distinguished adjacent vertices by sums, if every two adjacent vertices have different values of \( f \), the \( \sigma \) is called total neighbor distinguishing coloring by sums. In this paper, we determine exact value of these parameters for the Cartesian product, direct product and semi strong product of infinite paths, and finite graph of the semi strong product.

Keywords

Infinite path Finite graph Product graph Neighbor sum distinguishing total coloring Neighbor sum distinguishing total chromatic number
