Sharp estimates of the embedding constants for Besov spaces.
Sharp estimates are obtained for the rates of blow up of the norms of embeddings of Besov spaces in Lorentz spaces as the parameters approach critical values.
On the dependence of parameters in the equivalence theorem for the real method
We determine the exact dependence on of the constants in the equivalence theorem for the real interpolation method with pairs of -normed spaces.
