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 $$GR{M}_{\hat{I}}»(G)=\sum _{uv\in E}(deg(u)+\hat{I}»)(deg(v)+\hat{I}»),$$ where $\hat{I}»$ is an arbitrary real number and $deg…
