摘要：Recently the exponential Randic index e(chi) was introduced. The exponential Randic index of a graph G is defined as the sum of the weights e(1/root d(u)d(v)) of all edges uv of G, where d(u) denotes the degree of a vertex u in G. In this paper, we give sharp lower and upper bounds on the exponential Randic index of unicyclic graphs.
