Abstract :
We present some inequalities for operator space numerical radius of 2 × 2 block matrices on the matrix space Mn(X), when X is a numerical radius operator space. These inequalities contain some upper and lower bounds for operator space numerical radius.
Keywords :
Operator space , numerical radius operator space , operator space numerical radius , block matrix.
