We conclude the thesis with Chapter 5 by proposing some problems for further research on the extremal values of the first general Zagreb index, of the reformulated Zagreb index, and the extremal values of the unicyclic graphs of the general Randic index.

• 在论文的第五章里,我们对第一广义Zagerb指标的极值,改进的原始Zagreb指标的极值,以及单圈图的广义Randi(?) 指标的极值提出了一些可以进一步研究的问题。
