ABSTRACT
Let and be the polar decompositions of S and T in , respectively. In this paper we study solutions of operator equations which have similar real and positive parts with both the similarities implemented by a single invertible operator. Moreover, we investigate various properties of such solutions S and T.

关于满足实部和正部相似的算子方程的解
摘要
让和是S和T的极性分解, 分别。在本文中,我们研究了具有相似实部和正部的算子方程的解,它们的相似性由单个可逆算子实现。此外,我们研究了此类解决方案S和T的各种性质。
