论文摘要
最近，Li等人。 [应用。数学。计算。 382（2020）125335]提出了确定源自$ s_n \ times k_2 $的图形的Kirchhoff索引和乘法学度 - kirchhoff索引，这是Star $ s_n $的Catersian产品和完整的Graph $ k_2 $。在本文中，我们完全解决了这个问题。也就是说，对于从$ s_n \ times k_2 $获得的某些图，获得了Kirchhoff索引，乘法度kirchhoff索引的显式封闭形式公式。
Recently, Li et al. [Appl. Math. Comput. 382 (2020) 125335] proposed the problem of determining the Kirchhoff index and multiplicative degree-Kirchhoff index of graphs derived from $S_n \times K_2$, the Catersian product of the star $S_n$ and the complete graph $K_2$. In the present paper, we completely solve this problem. That is, the explicit closed-form formulae of Kirchhoff index, multiplicative degree-Kirchhoff index, and number of spanning trees are obtained for some graphs derived from $S_n \times K_2$.
