Survey on nullity of graphs

摘要: 综述无向简单图零度问题近年来所取得的研究进展.~该问题不仅对于深入了解图的各种性质有重要意义, 而且在化学上能反映分子的稳定性. 具体介绍了二部图、树、单圈图、双圈图和树的线图等图类的结果, 还讨论了大零度图等问题.Abstract: This paper gave a review of recent developments in the study of nullities of undirected simple graphs. The problem on nullity is very interesting in characterizing all kinds of properties of graphs as well as in determination of the stability of a molecule in chemistry. The results on bipartite graphs, trees, unicyclic graphs, bicyclic graphs, line graphs of trees were introduced. And thegraphs with large nullities were discussed.
