Abstract

In this paper, first Zagreb and second Zagreb matrices are defined for weighted graphs and accordingly the first Zagreb and second Zagreb energy of weighted graphs are introduced. Moreover, some upper and lower bounds are presented for Zagreb energy of positive definite matrix weighted graphs. Also some bounds are obtained for number weighted and unweighted graphs.
