摘要：

In this paper, several inequalities involving the Hilbert-Schmidt numerical radius inequalities for 2 x 2 operator matrices operators are established. In particular, we obtain some generalizations and refinements of earlier inequalities. Some upper and lower bounds for the Hilbert-Schmidt numerical radius inequalities for 2x2 operator matrices operators is also given.
