Abstract

In this paper boundedness of a weighted composition Lambert-type operator T = M w EM u C φ acting between two different L p (Σ) spaces is characterized using some properties of conditional expectation operator. Moreover, we establish criteria for hyponormality for these types of operators on L 2(Σ).
