Inequalities for linear functionals and numerical radii on -algebras
Pintu Bhunia
Let be a unital -algebra with unit . We develop several inequalities for a positive linear functional on and obtain several bounds…
Numerical Radius Inequalities via Orlicz function
Pintu Bhunia, Raj Kumar Nayak
Employing the Orlicz functions we extend the Buzano's inequality which is a refinement of the Cauchy-Schwarz inequality. Also using the Orlicz functions we obtain several numerical…
-Davis-Wielandt Radius Bounds of Semi-Hilbertian Space Operators
Messaoud Guesba, Somdatta Barik, Pintu Bhunia +1
Consider is a complex Hilbert space and is a positive operator on The mapping $\langle\cdot,\cdot\rangle_A: \mathcal{H}\times \mathcal{H} \to \math…
Sharper bounds for the numerical radius of operator matrices II
Pintu Bhunia
Let be an operator matrix where each is a bounded linear operator on a complex Hilbert space . With other numerical radius bounds via…
Schatten -norm and numerical radius inequalities with applications
Pintu Bhunia, Satyajit Sahoo
We develop a new refinement of the Kato's inequality and using this refinement we obtain several upper bounds for the numerical radius of a bounded linear operator as well as the p…
Norm Inequalities for Hilbert space operators with Applications
Pintu Bhunia
Several unitarily invariant norm inequalities and numerical radius inequalities for Hilbert space operators are studied. We investigate some necessary and sufficient conditions for…
