| Abstract: | 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. |
