On Second Order Graph Indices of Certain OTIS Networks

Motivated by the chemical applications of higher-order connectivity index (or Randic index), we consider here the higher-order Inverse sum indeg index of a graph. In study, physico-chemical properties and graph indices are used to predict the bioactivity of chemical compounds. In this paper, we derive analytical closed results for the second order Inverse sum indeg index, second order first Zagreb index and connectivity index for the Biswapped networks , , and graphs.
