Davis-Wielandt-Berezin radius inequalities of Reproducing kernel Hilbert space operators

Anirban Sen, Pintu Bhunia, Kallol Paul

Several upper and lower bounds of the Davis-Wielandt-Berezin radius of bounded linear operators defined on a reproducing kernel Hilbert space are given. Further, an inequality invo…

Development of the Berezin number inequalities

Pintu Bhunia, Anirban Sen, Kallol Paul

We present new bounds for the Berezin number inequalities which improve on the existing bounds. We also obtain bounds for the Berezin norm of operators as well as the sum of two op…

Improvement of numerical radius inequalities

Pintu Bhunia, Kallol Paul

We develop upper and lower bounds for the numerical radius of off-diagonal operator matrices, which generalize and improve on the existing ones. We also show that if $A…

Numerical radius inequalities for products and sums of semi-Hilbertian space operators

Pintu Bhunia, Kais Feki, Kallol Paul

New inequalities for the -numerical radius of the products and sums of operators acting on a semi-Hilbert space, i.e. a space generated by a positive semidefinite operator ,…
