On subspaces of and extreme contraction in
Shamim Sohel, Debmalya Sain, Kallol Paul
We investigate different possiblities of subspaces of the space in terms of whether the subspaces are polyhedral or not. We further study finite-dimensional subspac…
Numerical radius inequalities of sectorial matrices
Pintu Bhunia, Kallol Paul, Anirban Sen
We obtain several upper and lower bounds for the numerical radius of sectorial matrices. We also develop several numerical radius inequalities of the sum, product and commutator of…
Euclidean operator radius inequalities of a pair of bounded linear operators and their applications
Suvendu Jana, Pintu Bhunia, Kallol Paul
We obtain several sharp lower and upper bounds for the Euclidean operator radius of a pair of bounded linear operators defined on a complex Hilbert space. As applications of these…
Numerical radius inequalities for tensor product of operators
Anirban Sen, Pintu Bhunia, Kallol Paul
The two well-known numerical radius inequalities for the tensor product acting on , where and are bounded linear operators defi…
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…
