Abstract:
The energy of a graph is defined as the sum of the absolute values of all eigenvalues of the graph. Let T-n denote the set of trees with n vertices. When n >= 6, for a given integer Delta epsilon[3,n-2], we characterize the tree in T-n with maximum degree Delta and maximal energy. Furthermore, for inverted right perpendicularn+1/3inverted left peropendicular <=Delta(T)<= n-2 and n >= 7,thetreein T-n with maximum degree Delta and minimal energy is also determined.
