Some properties of the eigenvalues of the sum geometric arithmetic means matrix of graphs

الملخص

 In this paper, we study some properties of the eigenvalues of sum geometric arithmetic energy of graphs and we obtain the values of some coefficients of the characteristic poly nominal of the sum geometric arithmetic means matrix by using some methods. The inverse of the sum geometric arithmetic means matrix of some graphs are also obtained.

Keywords : The sum geometric arithmetic means matrix of a graph G. The characteristic polynomial of the sum geometric arithmetic means matrix of a graph G.
