Quantitative analysis of optimal Sobolev-Lorentz embeddings with $α$ -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 $ℓ_{p_{n}}$ and $ℓ_{q_{n}}$ are equivalent and also describe condi…
