    Comparison of the Wiener and Kirchhoff Indices of Random Pentachains by Shouliu Wei, Wai Chee Shiu, Xiaoling Ke, Jianwu Huang

    Published 2021-01-01
    “…In this paper, explicit formulae for the expected values of the Wiener and Kirchhoff indices of random pentachains are derived by the difference equation and recursive method. Based on these formulae, we then make comparisons between the expected values of the Wiener index and the Kirchhoff index in random pentachains and present the average values of the Wiener and Kirchhoff indices with respect to the set of all random pentachains with n pentagons.…”
