Maximal noncompactness of embeddings into Marcinkiewicz spaces

open access: yesAnnali di Matematica Pura ed Applicata (1923 -)
Abstract 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 space. The main result is a general principle from which it can be derived that such operators are almost always maximally noncompact in the sense ...

Anisotropic nonlinear elliptic systems with measure data and anisotropic harmonic maps into spheres

open access: yesElectronic Journal of Differential Equations, 2006
We prove existence results for distributional solutions of anisotropic nonlinear elliptic systems with a measure valued right-hand side. The functional setting involves anisotropic Sobolev spaces as well as weak Lebesgue (Marcinkiewicz) spaces. In a

Boundedness of commutators of variable Marcinkiewicz fractional integral operator in grand variable Herz spaces

open access: yesJournal of Inequalities and Applications
Let S n − 1 $\mathbb{S}^{n-1}$ denote unit sphere in R n $\mathbb{R}^{n}$ equipped with the normalized Lebesgue measure. Let Φ ∈ L s ( S n − 1 ) $\Phi \in L^{s}(\mathbb{S}^{n-1})$ be a homogeneous function of degree zero such that ∫ S n − 1 Φ ( y ′ ) d σ

Marcinkiewicz-Zygmund and interpolating families on the ball

open access: yesJournal of Inequalities and Applications
This paper examines points and weights on the unit ball B d $\mathbb{B}^{d}$ that satisfy L p $L_{p}$ , 0 < p ≤ ∞ $0< p\le \infty $ , Marcinkiewicz-Zygmund inequalities and interpolating inequalities with respect to a doubling weight.
