On the Sigma Value and Sigma Range of the Join of a Finite Number of Even Cycles of the Same Order
Let c be a vertex coloring of a simple; connected graph G that uses positive integers for colors. For a vertex v of G; the color sum of v is the sum of the colors of the neighbors of v. If no two adjacent vertices of G have the same color sum; then c is called a sigma coloring of G. The sigma chroma...
