The paper presents the nullity set of all bicyclic graphs of order(n(n≥6)) which is[0,n-4],and all the bicyclic graphs of order n(n≥9) with η(G)=n-4 and all the bicyclic graphs of order n(n≥ 10) with η(G)=n-5.
在此确定了所有n阶(n≥6)双圈图的零度集合是[0,n-4],并且刻画了η(G)=n-4的所有n阶(n≥9)双圈图,以及η(G)=n-5的所有n阶(n≥10)双圈图。
Theory of zero measure set is an important and difficult question in measure theory.
以法国数学家波莱尔的有关工作为核心,重点考察了他提出零测集的思想背景,提出零测集渐近测度和稀疏度的思想演变过程、思想方法及影响。
