摘要：
In this paper, we obtain some Berezin number and Berezin norm inequalities involving Moore-Penrose inverse of bounded linear operators and also study some inequalities for sums and products of operators on reproducing kernel Hilbert spaces. These inequalities improve and generalize some earlier related inequalities.
