论文摘要
本文的主要目的是为$ \ mathbb {a} $ - $ 2 \ times 2 $ 2 $运算符矩阵建立几个新的上限和下限，其中$ \ mathbb {a} $是$ 2 \ times 2 $ diagonal operator矩阵，其diagonal operrix的diagonal otrix的diagonal Ettrories的diagonal Entries是阳性限制了biffed bunded figed operator oper $ $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ a。
The main goal of this article is to establish several new upper and lower bounds for the $\mathbb{A}$-numerical radius of $2\times 2$ operator matrices, where $\mathbb{A}$ be the $2\times 2$ diagonal operator matrix whose diagonal entries are positive bounded operator $A$.
