摘要:
The first Zagreb index M-1 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 of the underlying molecular graph. We present upper bounds for M-1, and M-2 in terms of the number of vertices, number of edges, minimum vertex degree and maximum vertex degree.
