fill-in and operations of graphs
收藏 引用
Science China Mathematics 1995年 第7期38卷 777-788页
作者: 原晋江 Department of Mathematics Zhengzhou University Zhengzhou 450052 China
This paper establishes some local optimal fill-in theorems of graphs. The fill-in number of composite graphs is studied. An application of the local optimal fill-in theorems of graphs is given.

Weak-quasi-bandwidth and forward-bandwidth of graphs
收藏 引用
Science China Mathematics 1996年 第2期39卷 148-162页
作者: 原晋江 Department of Mathematics Zhengzhou University Zhengzhou 450052 China
Concepts of weak-quasi-bandwidth and forward-bandwidth of graphs are introduced. They are used to studythe following problems in graph theory: bandwidth, topological bandwidth, fill-in, profile, path-width, tree-width.
