Abstract
Let G=(V,E)be a simple graph,the second geometric-arithmetic indices defined as Σ2 √nunv/(nu+nv)where n(u)(n(v))of vertices of G lying closer to the vertex u(v)than to the vertex v(u)for the edge uv.In this paper,we transformed three kinds of bicyclic graphs,analyzed and determined the bicyclic graphs with the minimum GA2.关键词
