VIEWING *-MULTIPLICATION OPERATORS BETWEEN ORLICZ SPACES

jahangir cheshmavar, Seyed Kamel Hosseini

Abstract


In this paper, Lambert multipliers acting between Orlicz spaces are characterized based on some properties of conditional expectation operators. We provide a necessary and sufficient condition for the *-multiplication operators to have closed range. Finally, a necessary condition for Fredholmness of these type of operators will be investigated.
