Non-improvability of sharp endpoint estimates
Zdeněk Mihula, Luboš Pick, Armin Schikorra
For an integer and the parameter , the Riesz potential is known to take boundedly into , 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…
Potential trace inequalities via a Calderón-type theorem
Zdeněk Mihula, Luboš Pick, Daniel Spector
In this paper we develop a general theoretical tool for the establishment of the boundedness of notoriously difficult operators (such as potentials) on certain specific types of re…
Maximal noncompactness of embeddings into Marcinkiewicz spaces
Jan Malý, Zdeněk Mihula, Vít Musil +1
We develop a new functional-analytic technique for investigating the degree of noncompactness of an operator defined on a quasinormed space and taking values in a Marcinkiewicz spa…
Maximal noncompactness of limiting Sobolev embeddings
Jan Lang, Zdeněk Mihula, Luboš Pick
We develop a new method suitable for establishing lower bounds on the ball measure of noncompactness of operators acting between considerably general quasinormed function spaces. T…
