Improvements of Berezin number inequalities

Abstract: In this paper, we generalize several Berezin number inequalities involving product of operators, which acting on a Hilbert space H (Ω). Among other inequalities, it is shown that if A, B are positive operators and X is any operator, then ber r (H α (A, B)2010 Mathematics Subject Classification.

“…For our purpose, we set the Berezin norm of an operator as A ber supA kλ Therefore, the Berezin symbol uniquely determines the operator. Some excellent results about the Berezin number were found in [4,5,13,[25][26][27] very recently. Among many techniques in obtaining numerical radius and Berezin number inequalities is the study of certain scalar ones.…”

“…More information about numerical range and numerical radius can be found in [6,7,9,18,19,21]. Using the Hardy-Hilbert type inequalities and some well-known inequalities, some important results about the Berezin number inequalities were obtained in [2,3,10,22,[24][25][26][27][28].…”
