| 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.
