摘要：
For a connected cubic graph G of order n, we prove the existence of two disjoint dominating sets D1 and D2 with \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${|D_1|+|D_2|\leq \frac{157}{198}n+\frac{8}{9}}$$\end{document}.
