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,而且有很好的化学应用背景.具体介绍了二部图、树、单圈图、双圈图和树的线图等的零度刻划,还讨论了大零度图等问题.
This paper gave a review of recent developments in the study of nullities of undirected simple graphs. The nullity problem is very interesting in characterizing all graphs as well as in determination of the instability of a molecule in chemistry. Nullities of bipartite graphs, cycle graphs, bicycle graphs, tree graphs, line graphs of trees, and graphs with large nullities were discussed.
