Topological Indices and f-Polynomials on Some Graph Products

Topological Indices and f-Polynomials on Some Graph Products

We obtain inequalities involving many topological indices in classical graph products by using the f-polynomial. In particular, we work with lexicographic product, Cartesian sum and Cartesian product, and with first Zagreb, forgotten, inverse degree and sum lordeg indices.
