摘要：
Let MG(i,n) be a connected molecular graph without multiple edges on n vertices whose the minimum degree of vertices is I, where 1 <= i <= 4. One of the newest topological indices is the first Geometric-Arithmetic index. In this paper we determine the graph with the minimum and. the maximum value of first Geometric-Arithmetic index in the family of graphs MG(i,n), 1 <= i <= 3.
