چکیده
|
We introduce a fast method of computing the topological charge indices of simple graphs (molecules) which does not require matrices of large sizes. for the case of trees, we give a compact formula and in the general case we obtain upper and lower bounds for the charge indices. we give concrete examples of trees and molecules with their charge indices computed using our method.
