F-index of Total Transformation Graphs (1606.05989v1)
Published 20 Jun 2016 in cs.DM
Abstract: The F-index of a graph $G$ is the sum of the cubes of the degrees of the vertices of $G$. In this paper, explicit expressions for the F-index of different transformation graphs of type ${{G}{xyz}}$ with $x, y, z\in {-, + }$ are obtained. F-index for semitotal point graph and semitotal line graph are also obtained here.
