1. INEQUALITIES INVOLVING BEREZIN NORM AND BEREZIN NUMBER OF HILBERT SPACE OPERATORS.

Author

Subjects

Abstract

This paper presents several Berezin number and norm inequalities for Hilbert space operators. These inequalities improve some earlier related inequalities. Among other inequali- ties, it is shown that if A is a bounded linear operator on a Hilbert space, then ... where R = max{t, 1-t} and 0 ≤ t ≤ 1. [ABSTRACT FROM AUTHOR]

Abstract

This article considers the class of convex functions and derives further Jensen-Mercer'stype inequalities. The obtained results improve and generalize some known inequalities. A reverse of Jesnen-Mercer's inequality for scalars and operators is also given. As an application, we provide a new and non-trivial inequality related to the Wigner-Yanase-Dyson function and the logarithmic mean. [ABSTRACT FROM AUTHOR]
