The expected values for the Gutman index, Schultz index, multiplicative
degree-Kirchhoff index and additive degree-Kirchhoff index of a random
cyclooctatetraene chain
Abstract
In this paper, we mainly solve the explicit analytical expressions for
the expected values of the Gutman index, Schultz index, multiplicative
degree-Kirchhoff index and additive degree-Kirchhoff index of a random
cyclooctatetraene chain with $n$ octagons. We also obtain the average
values of these four indices with respect to the set of all these
cyclooctatetraene chains.
