| Abstract | In this article, we discuss measure theoretic characterizations for weighted composition operators in some operator classes on L2(Σ) such as, n-power normal, n-power quasi-normal, k-quasi-paranormal and quasi-class A. Then we show that weighted composition operators can separate these classes. |
