Further results on Berezin number inequalities and related problems


Satyajit Sahoo, Ulaş Yamancı




In this article, we obtain certain Berezin number inequalities which extend certain earlier existing results in the literature. Also, we give some reverse Berezin number inequalities for normal operators on reproducing kernel Hilbert spaces. Moreover, we characterize the projection operators and the partial isometry operators in terms of Berezin number.
