Interpolation of Rational Approximation Spaces Belonging to the Besov Class

The Peetre real interpolation method is realized for the Besov class of spaces of analytic functions on the circle. We obtain a description of interpolation norms with the help of difference-differential constructions. We consider rational approximation spaces in the BMOA and H p norms.
