Unbounded weighted conditional expectation operators

Abstract

In this note basic properties of unbounded weighted conditional expectation operators are investigated. A description of polar decomposition and quasinormality in this context are provided. Also, we study hyperexpan- sive weighted conditional expectation operators.
