Abstract

We investigate an operator on a Hilbert space, it is useful to determine the operators. We present commutants of composition operators acting on the Hardy space of analytic functions on the unit disk. We include some results about semi groups of weighted composition operators. We examine the weighted composition operators on H2 are self-adjoint. We respective the essential norm, the spectral radius, and the essential spectral radius of an operator. We applied some examples.
