Research Abstract

Main object of this research is to investigate the topological structure of composition operators on various analytic and harmonic function spaces. The product of composition operators also is trivially a composition operator, but the sum and the difference of them are not clear. We here obtain results for linear combinations of composition operators to act compactly between two function spaces.
