Berezin number inequalities for operators
TL;DR: In this paper, it was shown that if A, B, X are bounded linear operators on a Hilbert space ℋ, then ber(AX±XA)⩽ber12(A*A+AA*)12(X*X+X+XX*) $${\\bf{ber}}(AX \\pm XA)
Journal ArticleDOI
Reverses and variations of Heinz inequality
TL;DR: In this article, the reverse Heinz-type inequalities involving Hadamard product of the formin which is a unitarily invariant norm were established for positive definite matrices.
Journal ArticleDOI
Reverse Young-type inequalities for matrices and operators
TL;DR: In this article, the reverse Young-type inequalities for the Hilbert-Schmidt norm as well as any unitarily invariant norm were established. And they were shown to hold for trace, determinant and singular values.

TL;DR: In this paper, it was shown that ωr(T)≤2r−2 √ f2r(|X|)+g2r (|Y∗|)√ 12 √ 12, where X,Y are bounded linear operators on a Hilbert space H, r≥1, and f, g are nonnegative continuous functions satisfying the relation f(t)g(t)=t (t∈[0,∞)).
