SOME GENERAL NUMERICAL RADIUS INEQUALITIES FOR THE OFF-DIAGONAL PARTS OF 2 × 2 OPERATOR MATRICES
Keywords:
numerical radius, operator matrix, off-diagonal part, Cartesian decomposition, Jensen’s inequality, mixed Schwarz inequalityAbstract
We give some sharp inequalities involving powers of the numerical radii for the off-diagonal parts of 2 × 2 operator matrices. These inequalities, which are based on some classical convexity inequalities for the nonnegative real numbers, generalize earlier numerical radius inequalities.
