Özet

In this paper, we provide the new Berezin radius inequalities on the space of operators defined on a functional Hilbert space. By using these inequalities, we obtain various upper bounds for the Berezin radius of functional Hilbert space operators. We prove, in particular, the following sharp upper bound(Formula presented) for arbitrary T, S ∈ B (H) and ξ ≥ 0. Other related issues are also discussed.
