Bounds for zeros of a polynomial using numerical radius of Hilbertian space operators
Pintu Bhunia, Santanu Bag, Kallol Paul
We obtain bounds for the numerical radius of operator matrices which improve on the existing bounds. We also show that the inequalities obtained here generalize the ex…
Bounds of numerical radius of bounded linear operator using -Aluthge transform
Santanu bag, Pintu Bhunia, Kallol Paul
We develop a number of inequalities to obtain bounds for the numerical radius of a bounded linear operator defined on a complex Hilbert space using the properties of -Aluthge tr…
Numerical radius inequalities and its applications in estimation of zeros of polynomials
Pintu Bhunia, Santanu Bag, Kallol Paul
We present some upper and lower bounds for the numerical radius of a bounded linear operator defined on complex Hilbert space, which improves on the existing upper and lower bounds…
Numerical radius inequalities of operator matrices with applications
Pintu Bhunia, Santanu Bag, Kallol Paul
We present upper and lower bounds for the numerical radius of operator matrices which improves on the existing bound for the same. As an application of the results obt…
