Abstract

Given a graph , the general sum-connectivity index is defined as , where (or ) denotes the degree of vertex (or ) in the graph and is a real number. In this paper, we obtain the sharp bounds for general sum-connectivity indices of several graph transformations, including the semitotal-point graph, semitotal-line graph, total graph, and eight distinct transformation graphs , where .
