Two topological indices (Gutman index and Schultz index) for random phenylene chains have exact formulae for expected values.
Abstract
The Gutman index and Schultz index are two topological indices. In this paper, we first give exact formulae for the expected values of the Gutman index and Schultz index of random phenylene chains, and we will also get the average values of the Gutman index and Schultz index in phenylene chains.
