• More accurate numerical radius inequalities (I) (2019, background): “uch inequalities are important as one can have upper or lower bounds of one quantity in terms of the other. Consequently, having sharper bounds is highly demanded in this field. We refer the reader to [1, 2, 4, 5, 7, 9, 10, 11] as a sample of treatments of this interest. In [7], Kittaneh proved that ”
• Cartesian decomposition and Numerical radius inequalities (2015, methodology): “herein). Several investigations on norm and numerical radius inequalities involving the Cartesian decomposition may be found in the literature, among them we would like to refer the reader to [4] and [7]. In this note, we show that if T = H + iK is the Cartesian decomposition of T ∈ B(H ), then for ”
• Numerical radius inequalities and its applications in estimation of zeros of polynomials (2019, background): “s on the bound obtained by Abu-Omar and Kittaneh [1], namely, w4(T) ≤ 1 4 w2(T2) + 1 4 w(T2)kPk+ 1 16 kPk2. Abu-Omar and Kittaneh [1] also proved that this bound is better than the bounds obtained in [13, 12] w(T) ≤ 1 2 kTk+kT2k12 NUMERICAL RADIUS INEQUALITIES 3 and w2(T) ≤ 1 2 kPk. Dragomir [7] pro”
• A-numerical radius inequalities for semi-Hilbertian space operators (2019, methodology): “lity becomes an equality if T2 = 0. The second inequality becomes an equality if T is normal.
