Let denote the usual Hardy space of analytic functions on the unit disc . We prove that for every function there exists a linear operator defined on which is simultaneously bounded from to and from to such that . Consequently, we get the following results : 1) is a Calderon-Mitjagin couple; 2) for any interpolation functor , we have , where denotes the closed subspace of of all functions whose Fourier coefficients...
