On the properties of rearrangement-invariant quasi-Banach function spaces [PDF]

open access: yesNonlinear Analysis: Theory, Methods & Applications
This paper explores some important aspects of the theory of rearrangement-invariant quasi-Banach function spaces. We focus on two main topics. Firstly, we prove an analogue of the Luxemburg representation theorem for rearrangement-invariant quasi-Banach function spaces over resonant measure spaces.

Gagliardo–Nirenberg Inequality for rearrangement-invariant Banach function spaces [PDF]

open access: yesRendiconti Lincei, Matematica e Applicazioni, 2019
The classical Gagliardo–Nirenberg interpolation inequality is a well-known estimate which gives, in particular, an estimate for the Lebesgue norm of intermediate derivatives of functions in Sobolev spaces. We present an extension of this estimate into the scale of the general rearrangement-invariant Banach function spaces with the proof based on the ...

Approximation by polynomials in rearrangement invariant quasi Banach function spaces

open access: yesBanach Journal of Mathematical Analysis, 2012
The author deals with the approximation properties of certain linear polynomial operators in rearrangement-invariant quasi-Banach function spaces \(X\) with absolutely continuous norm under the assumption that \(X\) is \(p\) convex for some \(p\in(0,1]\).

On boundedness of the Hilbert transform on Marcinkiewicz spaces

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
We study boundedness properties of the classical (singular) Hilbert transform (Hf)(t) = p.v.1/π ∫R f(s)/(t − s) ds, acting on Marcinkiewicz spaces. The Hilbert transform is a linear operator which arises from the study of boundary values of the real and

Singular integral operators with operator-valued kernels, and extrapolation of maximal regularity into rearrangement invariant Banach function spaces [PDF]

open access: yesJournal of Evolution Equations, 2014
We prove two extrapolation results for singular integral operators with operator-valued kernels and we apply these results in order to obtain the following extrapolation of L p-maximal regularity: if an autonomous Cauchy problem on a Banach space has L p-maximal regularity for some p ∈ (1, ∞), then it has E w-maximal regularity for every rearrangement ...

Lebesgue's Differentiation Theorems in R.I. Quasi-Banach Spaces and Lorentz Spaces Γp,w

open access: yesJournal of Function Spaces and Applications, 2012
The paper is devoted to investigation of new Lebesgue's type differentiation theorems (LDT) in rearrangement invariant (r.i.) quasi-Banach spaces E and in particular on Lorentz spaces Γp,w={f:∫(f ...
