NUMERICAL RADIUS INEQUALITIES FOR CERTAIN ACCRETIVE-DISSIPATIVE MATRICES

Mona Sakkijha, Maryam M Alholi, Shatha Hasan

Abstract


In this paper, we present interesting lower bounds inequalities for numerical radius involving accretive-dissipative matrices. We also present several useful results for twoby two block matrices. An example to show sharpness of a proved theorem is also given.
