General randic index and geometrix-arithmetic related indices of certain special molecular graphs

Yun Gao, Li Liang, Wei Gao

Some chemical indices have been invented in theoretical chemistry, such as Randic index and geometric-arithmetic index. In this paper, by virtue of strict mathematical deduction, we present the general Randic index, general geometric-arithmetic index and third geometric-arithmetic index of fan molecular graph, wheel molecular graph, gear fan molecular graph, gear wheel molecular graph, and their r-corona molecular graphs.
