Let B(H) be the space of all bounded linear operators on a complex Hilbert space H, and let A 1 , . . . , A n ∈ B(H). In this article, we obtain new upper bounds for n j=1 A j . Moreover, we establish and generalize inequalities for the operator norm of sums of bounded linear operators in Hilbert spaces.
