Abstract

In this paper, we study properties of operators which are power similar to complex symmetric operators. In particular, we prove that if T is power similar to a complex symmetric operator, then T is decomposable modulo a closed set (Formula Presented) if and only if R has the Bishop’s property (β) modulo S. Using the results, we get some applications of such operators.
