Generalized the Divisor Sum Tk-Function of Graph

Hariwan Fadhil M.Salih , Nechirvan Badal Ibrahim

Let G = (V, E) be a simple connected undirected graph. In this paper, we define generalized the divisor sum Tk-function of a graph which is the summation of the sum of divisor k-function of the degree of the vertices of a graph denoted by Tk(G) = P v2V(G) k(deg(v)) and determine the divisor sum Tk-function ...
