Resumen de Approximation spaces, limiting interpolation and Besov spaces

Fernando Cobos Díaz , Óscar Domínguez

• With the help of limiting interpolation we determine the spaces obtained by iteration of approximation constructions. Then we apply the reiteration formula and limiting interpolation to investigate several problems on Besov spaces, including embeddings in Lorentz�Zygmund spaces and distribution of Fourier coefficients.
