Abstract:

Using the method of graft transformation, this paper discussed the spectral radius of unicyclic graphs and their total graphs, meanwhile, the extreme graphs which reach the upper (lower)bounds were given respectively.

Key words: graph unicyclic graphs total graph spectral radius graft transformation
