Composite Operators on Atomic Orlicz Spaces

Dr. Shally Gupta

Abstract: In this paper we study composition operators on atomic measure spaces. The behaviour of composition operators on atomic measure spaces diers from that of composition operators on non-atomic measures spaces. Characterization for compact, fredholm, invertible and composition operators with closed ranges are studied in the paper.
