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 ,…
smoothness on polyhedral Banach spaces
Subhrajit Dey, Arpita Mal, Kallol Paul
We characterize smoothness of an element on the unit sphere of a finite-dimensional polyhedral Banach space. Then we study smoothness of an operator $T \in \mathbb{L}(\ell_…
Some remarks on orthogonality of bounded linear operators
Anubhab Ray, Debmalya Sain, Subhrajit Dey +1
We explore the relation between the orthogonality of bounded linear operators in the space of operators and that of elements in the ground space. To be precise, we study if $ T, A…
