摘要
Abstract
The first geometric arithmetic indices is a novel topological index in chemical graph theory.It has a wide range of application in chemistry.The first geometric arithmetic indices of line,total and subdivision graphs was investigated.By using the method of analyzing graph structure,the tight upper and lower bounds on first geometric arithmetic indices of line,total and subdivision graphs were presen-ted,and the graphs which first geometric arithmetic indices and satisfied these tight bounds were charac-terized.关键词
