Marcinkiewicz Integrals on Weighted Weak Hardy Spaces

Journal of Function Spaces, 2014
We prove that, under the condition Ω∈Lipα, Marcinkiewicz integral μΩ is bounded from weighted weak Hardy space WHwpRn to weighted weak Lebesgue space WLwpRn for maxn/n+1/2,n/n ...

Double Points Local Hardy-Littlewood Maximal Operator

Abstract and Applied Analysis, 2013
A double points local Hardy-Littlewood maximal operator Ma,b,k,loc is defined and investigated in Euclidean spaces. It is proved that Ma,b,k,loc is bounded on Lpw when p>1 and from L1w to L1,∞w with weight function w∈Aa,b,k,loc, the class of double ...

Entropy numbers of embeddings of function spaces with Muckenhoupt weights, III. Some limiting cases

Journal of Function Spaces and Applications, 2011
We study compact embeddings for weighted spaces of Besov and Triebel-Lizorkin type where the weight belongs to some Muckenhoupt Ap class. This extends our previous results [25] to more general weights of logarithmically disturbed polynomial growth, both ...

The scalar T1 theorem for pairs of doubling measures fails for Riesz transforms when p not 2

Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.
Abstract We show that for an individual Riesz transform in the setting of doubling measures, the scalar T1$T1$ theorem fails when p≠2$p \ne 2$: for each p∈(1,∞)∖{2}$ p \in (1, \infty) \setminus \lbrace 2\rbrace$, we construct a pair of doubling measures (σ,ω)$(\sigma, \omega)$ on R2$\mathbb {R}^2$ with doubling constant close to that of Lebesgue ...

The sharp A(p) constant for weights in a reverse-Holder class [PDF]

, 2009
Coifman and Fefferman established that the class of Muckenhoupt weights is equivalent to the class of weights satisfying the "reverse Holder inequality". In a recent paper V.

Operator‐Theoretic Probability Framework in Morrey Spaces With Applications to Option Price Dynamics

Journal of Mathematics, Volume 2026, Issue 1, 2026.
We develop a unified operator‐theoretic and probabilistic framework for a class of fractional and jump‐type evolution equations in the generalized Morrey spaces. The analysis is based on the semigroup theory and subordination principles which allow us for the treatment of nonlocal temporal dynamics and discontinuous effects.

Muckenhoupt Matrix Weights [PDF]

, 2021
We study matrix weights defined on the multivariate torus Td. Sufficient conditions for a matrix weight to be in the Muckenhoupt A2-class are studied, and two such sufficiency results obtained by S.

Weighted Hardy operators in the local generalized variable exponent weighted Morrey spaces and applications to differential operators

Partial Differential Equations in Applied Mathematics
We consider local generalized weighted Morrey spaces M{x0}p(⋅),ω,φ(Rn) with variable exponent p(x), φ is a weight and a general function ω(r) defining the Morrey-type norm.
