摘要
对Lipschitz算子对偶算子Tl*的数值半径进行了研究,得到当Lipschitz算子T达范的时候,Tl*的数值半径等于T的范数。
The numerical radius of Lipschitz dual operator,which is denoted by Tl*,is studied in this paper. The main result of this paper is that if the Lipschitz operator T attains its norm, then the numerical radius of Tl*is equal to its norm.
