Further results on the lower bound on reduced Zagreb index of trees

Milan Bašić, Aleksandar Ilić

For a graph $G$, the general reduced second Zagreb index is defined as $$GR{M}_{\lambda }(G)=\sum _{uv\in E}(deg(u)+\lambda )(deg(v)+\lambda ),$$ where $\lambda$ is an arbitrary real number and $deg(v)$…
