Optimal local embeddings of Besov spaces involving only slowly varying smoothness
Original language description
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-Karamata spaces. In particular, we improve results from Caetano et al. (2011), where the targets are (local) Lorentz-Karamata spaces. To derive such results, we apply limiting real interpolation techniques and weighted Hardy-type inequalities. (C) 2020 Elsevier Inc. All rights reserved.
