Abstract

The Kirchhoff index and degree-Kirchhoff index have attracted extensive attentions due to its practical applications in complex networks, physics, and chemistry. In 2019, Liu et al. [Int. J. Quantum Chem. 119 (2019) e25971] derived the formula of the degree-Kirchhoff index of linear octagonal-quadrilateral networks. In the present paper, we consider linear crossed octagonal-quadrilateral networks QnQ_n. Explicit closed-form formulas of the Kirchhoff index, the degree-Kirchhoff index, and the number of spanning trees of QnQ_n are obtained. Moreover, the Kirchhoff index (resp. degree-Kirchhoff index) of QnQ_n is shown to be almost 1/4 of its Wiener index (resp. Gutman index).
