摘要:

在给定阶数和固定匹配数或边覆盖数的连通图中,刻画了唯一代数连通度最小的图,并给出了代数连通度的两个下界.

英文摘要:

In this paper we characterize the unique graph whose algebraic connectivity is minimum among all connected graphs with given order and fixed matching number or edge covering number, and present two lower bounds for the algebraic connectivity in terms of the matching number or edge covering number.
