Sharp embeddings of Besov spaces involving only logarithmic smoothness
We use Kolyada´s inequality and its converse form to prove sharp embeddings of Besov spaces (involving the zero classical smoothness and a logarithmic smoothness with the exponent .beta.) into Lorentz-Zygmund s...

Sharp Embeddings of Besov Spaces with Logarithmic Smoothness
We present an elementary and direct approach to obtain sharp embeddings of Besov spaces with the classical smoothness and a logarithmic smoothness into Lorenz-Zygmund spaces. We cover both the sub-limiting...

Optimal local embeddings of Besov spaces involving only slowly varying smoothness
The aim of the paper is to establish (local) optimal embeddings of Besov spaces B-p,r(0,b) involving only a slowly varying smoothness b. In general, our target spaces are outside of the scale of Lorentz-Ka...

Characterizations of Besov and Triebel–Lizorkin spaces via averages on balls
.... The corresponding results for inhomogeneous Besov and Triebel–Lizorkin spaces are also obtained. These results, for the first time, give a way to introduce Besov and Triebel–Lizorkin spaces with any smoot...

Critical imbeddings with multivariate rearrangements
The paper deals with imbeddings of general spaces of Besov and Lizorkin-Triebel adapted to the character of smoothness of the imbedded spaces. Sharp limiting exponential Orlicz and Lorentz-Orlicz space...
