Generalized Euclidean operator radius inequalities of a pair of bounded linear operators

Suvendu Jana

Let $B (H)$ represent the $C^{*}$ -algebra, which consists of all bounded linear operators on $H,$ and let $N (.)$ be a norm on $ \mathbb{B}(\mathscr{H}…

Refinements of generalized Euclidean operator radius inequalities of 2-tuple operators

Suvendu Jana, Pintu Bhunia, Kallol Paul

We develop several upper and lower bounds for the $A$ -Euclidean operator radius of $2$ -tuple operators admitting $A$ -adjoint, and show that they refine the earlier related bounds.…

Estimations of Euclidean operator radius

Pintu Bhunia, Suvendu Jana, Kallol Paul

We develop several Euclidean operator radius bounds for the product of two $d$ -tuple operators using positivity criteria of a $2 \times 2$ block matrix whose entries are $d$ -tuple o…

Euclidean operator radius inequalities of $d$ -tuple operators and operator matrices

Suvendu Jana, Pintu Bhunia, Kallol Paul

In this paper, we develop several Euclidean operator radius inequalities of $d$ -tuple operators, as well as the sum and the product of $d$ -tuple operators. Also, we obtain a power…

Numerical radius inequalities and estimation of zeros of polynomials

Suvendu Jana, Pintu Bhunia, Kallol Paul

Let $A$ be a bounded linear operator defined on a complex Hilbert space and let $∣ A ∣ = (A^{*} A)^{1/2}$ be the positive square root of $A$ . Among other refinements of the well known num…

Improved inequalities for the numerical radius via Cartesian decomposition

Pintu Bhunia, Suvendu Jana, Mohammad Sal Moslehian +1

We develop various lower bounds for the numerical radius $w (A)$ of a bounded linear operator $A$ defined on a complex Hilbert space, which improve the existing inequality $w^2(A)\g…

Refined inequalities for the numerical radius of Hilbert space operators

Pintu Bhunia, Suvendu Jana, Kallol Paul

We present some new upper and lower bounds for the numerical radius of bounded linear operators on a complex Hilbert space and show that these are stronger than the existing ones.…
