摘要：

If G is a graph on n vertices, and d(i) is the degree of its i-th vertex, then the Randic matrix of G is the square matrix of order n whose (i, j)-entry is equal to 1/root d(i)d(j) if the i-th and j-th vertex of G are adjacent, and zero otherwise. In this note, we obtain some new lower and upper bounds for the Randic energy.
