Abstract

BANI-DOMI, Watheq  and  ALI BANI-AHMAD, Feras. New numerical radius inequalities for certain operator matrices. Proyecciones (Antofagasta) [online]. 2012, vol.31, n.3, pp.277-297. ISSN 0716-0917.  http://dx.doi.org/10.4067/S0716-09172012000300007.

In this paper we prove some upper and lower bounds for the numerical radius of the off-diagonal part of 3 X 3 operator matrices and some bounds for the numerical radius inequalities of the general 3 X 3 operator matrix.

Keywords : Numerical radius; Operator norm; Operator matrix; Inequality; Off-diagonal part.
