Multiplicative Sombor index of trees
For a graph Ώ, the multiplicative Sombor index is defined as Π_{SO}(Ω)=Π_{ab∈ε(Ω)} √(d²_Ω(a)+d²_Ω(b)), where d_Ώ(a) is the degree of vertex a. Liu [Liu, H. (2022). Discrete Mathematics Letters, 9, 80-85] showed that, when is a tree of order n, Π_{SO}( )≥Π_{SO}(Pₙ)=5(√8)ⁿ⁻³. We improved this result...
