Some useful lemmas on the edge Szeged index

Shengjie He

The edge Szeged index of a graph $G$ is defined as $S z_{e} (G) = uv \in E (G) \sum m_{u} (uv ∣ G) m_{v} (uv ∣ G)$ , where $m_{u} (uv ∣ G)$ (resp., $m_{v} (uv ∣ G)$ ) is the number of edges who…

On extremal cacti with respect to the edge revised Szeged index

Shengjie He, Rong-Xia Hao, Deming Li

Let $G$ be a connected graph. The edge revised Szeged index of $G$ is defined as $Sz^{\ast}_{e}(G)=\sum\limits_{e=uv\in E(G)}(m_{u}(e|G)+\frac{m_{0}(e|G)}{2})(m_{v}(e|G)+\frac{m_{0…
