Non-improvability of sharp endpoint estimates

Zdeněk Mihula, Luboš Pick, Armin Schikorra

For an integer $n$ and the parameter $γ \in (0, n)$ , the Riesz potential $I_{γ}$ is known to take boundedly $L^{1} (R^{n})$ into $L^{\frac{n}{n - γ}, \infty} (R^{n})$ , and also t…

The Persson--Stepanov theorem revisited

Amiran Gogatishvili, Luboš Pick, Hana Turčinová +1

We develop a new proof of the result of L.-E.~Persson and V.D.~Stepanov \cite[Theorems 1 and 3]{Per:02}, which provides a characterization of a Hardy integral inequality involving…

Fractional Orlicz-Sobolev embeddings into Campanato type spaces

Angela Alberico, Andrea Cianchi, Luboš Pick +1

Optimal embeddings for fractional Orlicz-Sobolev spaces into (generalized) Campanato spaces on the Euclidean space are exhibited. Embeddings into vanishing Campanato spaces are als…
