For a bounded linear operator, acting in the reproducing kernel Hilbert space H= H\left (Ω\right) H= H Ω over some set Ω Ω, its Berezin symbol (or Berezin transform) AA~ is defined …

In this article, we establish several Berezin number inequalities for the quadratic weighted operator geometric mean of operators on reproducing kernel Hilbert spaces and numerical …
We establish some upper bounds for Berezin number inequalities including inequalities for 2× 2 operator matrices and their off-diagonal parts. Among other inequalities, it is shown that …
In this paper, we obtain some Berezin number inequalities based on the definition of Berezin symbol. Among other inequalities, we show that if A, B be positive definite operators in B (H) …
In this work, the concept of the Davis-Wielandt Berezin number is introduced. Some upper and lower bounds for the Davis-Wielandt Berezin number are introduced. A connection …

We prove new Grüss type inequalities for the Berezin symbol of some operator products. As biproducts, we find new relations between the Berezin number, the Berezin norm and some …
