Edge szeged index of certain special molecular graphs

Li Yan Yongbin Zhu,Wei Gao, Li Junsheng

Szeged index and edge Szeged index are introduced to measure the characters of molecular graphs. These properties have potential applications in pharmaceutical field. In this paper, we determine theedgeSzeged index of fan molecular graph, wheel molecular graph, gear fan molecular graph, gear wheel molecular graph, and their r-corona molecular graphs.
