Research output: Contribution to journalArticlepeer-review

Abstract

We study the quasinormality of singular integral operators with Cauchy kernel on L 2. Moreover, we give characterizations for singular integral operators to be the square root of a self-adjoint operator and an isometry, respectively. Furthermore, we consider the condition for singular integral operators to be D -operators. We provide several results and examples of such operators as applications.
