Characterization of the boundedness of the segment multiplier on weighted Lebesgue spaces
Miguel F. Barea-Fernández, Jan Lang, Javier Soria
For , we characterize the boundedness of the segment multiplier on by a large-scale Muckenhoupt condition, obtained by restricting the classical conditio…
Characterization of the boundedness of the segment multiplier on rearrangement-invariant spaces
Miguel F. Barea-Fernández, Ron Kerman, Jan Lang +1
Given a rearrangement-invariant (r.i.) space X, we show that the segment multiplier, the truncated Hilbert transform, and the discrete Hilbert transform (on the associated discreti…
Limit as of -Harmonic functions for unbounded
Behzad Djafari Rouhani, Jan Lang, Osvaldo Méndez
It is shown that if is a sequence of continuous, unbounded exponents on a bounded, smooth domain with and $p_n\rightar…
Quantitative analysis of optimal Sobolev-Lorentz embeddings with -homogeneous weights
Petr Gurka, Jan Lang, Zdeněk Mihula
Optimal weighted Sobolev-Lorentz embeddings with homogeneous weights in open convex cones are established, with the exact value of the optimal constant. These embeddings are non-co…
Embeddings between sequence variable Lebesgue spaces, strict and finitely strict singularity
Jan Lang, Ales Nekvinda
In this paper, we provide necessary and sufficient conditions under which two sequence variable Lebesgue spaces and are equivalent and also describe condi…
Different degrees of non-compactness for optimal Sobolev embeddings
Jan Lang, Zdeněk Mihula
The structure of non-compactness of optimal Sobolev embeddings of -th order into the class of Lebesgue spaces and into that of all rearrangement-invariant function spaces is qua…
