Refinement of seminorm and numerical radius inequalities of semi-Hilbertian space operators
Pintu Bhunia, Kallol Paul, Raj Kumar Nayak
We give new inequalities for -operator seminorm and -numerical radius of semi-Hilbertian space operators and show that the inequalities obtained here generalize and improve o…
Improvement of -numerical radius inequalities of semi-Hilbertian space operators
Pintu Bhunia, Raj Kumar Nayak, Kallol Paul
Let be a complex Hilbert space and let be a positive operator on . We obtain new bounds for the -numerical radius of operators in semi-Hilbertian…
Refinements of A-numerical radius inequalities and their applications
Pintu Bhunia, Raj Kumar Nayak, Kallol Paul
We present sharp lower bounds for the A-numerical radius of semi-Hilbertian space operators. We also present an upper bound. Further we compute new upper bounds for the -numeric…
Estimations of zeros of a polynomial using numerical radius inequalities
Pintu Bhunia, Santanu Bag, Raj Kumar Nayak +1
We present new bounds for the numerical radius of bounded linear operators and operator matrices. We apply upper bounds for the numerical radius to the Frobenius compan…
