摘要：
For a (molecular) graph G, the first Zagreb indices M, is equal to the sum of the squares of the degrees of the vertices, and the second Zagreb index M-2 is equal to the sum of the products of the degrees of pairs of adjacent vertices. We give some new bounds for Zagreb indices and provide a matrix-representation and its applications.
