Hardy's inequalities for monotone functions on partially ordered measure spaces

Nicola Arcozzi, Sorina Barza, Josep L. Garcia-Domingo +1

We characterize the weighted Hardy's inequalities for monotone functions in $R_{+}^{n} .$ In dimension $n = 1$ , this recovers the classical theory of $B_{p}$ weights. For $n > 1$ , t…

Mixed norm and multidimensional Lorentz spaces

Sorina Barza, Anna Kaminska, Lars-Erik Persson +1

In the last decade, the problem of characterizing the normability of the weighted Lorentz spaces has been completely solved (\cite{Sa}, \cite{CaSoA}). However, the question for mul…

Multidimensional rearrangement and Lorentz spaces

Sorina Barza, Lars-Erik Persson, Javier Soria

We define a multidimensional rearrangement, which is related to classical inequalities for functions that are monotone in each variable. We prove the main measure theoretical resul…
