الملخص

There are plentiful ways to duplicate a graph (network), such as splitting, shadow, mirror, and total graph. In this paper, we derive an evident formula of the complexity, a number of spanning trees, of the closed helm graph, the mirror graph of the path and cycle, the total graph of the path, the cycle, and the wheel. Furthermore, we got an explicit formula for the splitting of a special family of graphs such as path, cycle, complete graph Kn, complete bipartite graph Kn,n, prism, diagonal prism, and the graphs obtained from the wheel and double wheel by splitting the vertices on their rim. Finally, an obvious formula for the complexity of k− shadow graph for some graphs such as the path, the cycle, the wheel, the complete graph, and the fan graph Fn has been obtained. These formulas have been discovered by employing techniques from linear algebra, orthogonal polynomials, and matrix theory
