Abstract
Suppose G be a graph with the set of vertex V(G) and set of edge E(G), and let du P denote the vertex degree u ∈ V(G). The first general Zagreb index (or general Zerothـorder Randic index) is defined as where is the order of vertices and .The generalized connectivity index , is defined as The general sum-connectivity index as . . In this paper, we investigate the relationships between generalized and several topological indices with sum graphs of groups
