Counting Triangles to Sum Squares
The article presents information about the mathematical research of Joe DeNaio, professor of mathematics at Kennesaw State University, Georgia. It mentions that his professional interest includes the realization of combinatorial identities via graph theory and chessboard puzzles. It also states that counting complete sub graphs of three vertices in complete graphs, yields combinatorial identities for sums of squares of integers, odd integers and even integers.
