Computing the forgotten topological index of four operations on graphs
For a (molecular) graph, the first Zagreb index is equal to the sum of squares of the degrees of vertices, and the second Zagreb index is equal to the sum of the products of the degrees of pairs of adjacent vertices. The -index of a graph denoted by or is defined as the sum of cubes of the degrees o...
