Özet
The Berezin transform T and the Berezin radius of an operator T on the reproducing kernel Hilbert space H (Q) over some set Q with the reproducing kernel Kη are defined, respectively, by (Formula Presented) We study several sharp inequalities by using this bounded function ˜T, involving powers of the Berezin radius and the Berezin norms of reproducing kernel Hilbert space operators. We also give some inequalities regarding the Berezin transforms of sum of two operators.
