Abstract
Let (Formula presented.) and (Formula presented.) be the polar decompositions of S and T in (Formula presented.), 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.
