Multilinear BMO Estimates for the Commutators of Multilinear Fractional Maximal and Integral Operators on the Product Generalized Morrey Spaces

International Journal of Analysis and Applications, 2019
In this paper, we establish multilinear BMO estimates for commutators of multilinear fractional maximal and integral operators both on product generalized Morrey spaces and product generalized vanishing Morrey spaces, respectively.

An embedding theorem for Campanato spaces

Electronic Journal of Differential Equations, 2002
The purpose of this paper is to give a Sobolev type embedding theorem for the spaces $mathcal{L}_{p,q}^{lambda,s}(mathbb{R}^{n})$. The homogeneous versions of these spaces contain well known spaces such as the Bounded Mean Oscillation spaces (BMO) and ...

Function spaces between BMO and critical Sobolev spaces

Journal of Functional Analysis, 2006
The author introduces the function spaces \(D_\ell(\mathbb{R}^d)\) which are based on a regularity property for the critical Sobolev spaces \(W^{s,p}(\mathbb{R}^d)\) with \(sp=d\). The spaces \(D_\ell(\mathbb{R}^d)\) contain all the critical Sobolev spaces. The spaces \(D_\ell(\mathbb{R}^d)\) contain neither \(\text{BMO}(\mathbb{R}^d)\) nor \(\text{VMO}

Higher Order Commutators of Fractional Integral Operator on the Homogeneous Herz Spaces with Variable Exponent

Journal of Function Spaces and Applications, 2013
By decomposing functions, we establish estimates for higher order commutators generated by fractional integral with BMO functions or the Lipschitz functions on the homogeneous Herz spaces with variable exponent.

Central BMO spaces with variable exponent

, 2017
In this paper, the central BMO spaces with variable exponent are introduced. As an application, we characterize these spaces by the boundedness of commutators of Hardy operator and its dual operator on variable Lebesgue spaces. The boundedness of vector-valued commutators on Herz spaces with variable exponent are also considered.

Function spaces of BMO and Campanato type

Electronic Journal of Differential Equations, 2002
To obtain the Littlewood-Paley characterization for Campanato spaces $mathcal{L}^{2,lambda}$ modulo polynomials (which contain as special case the John and Nirenberg space $BMO$), we define and study a scale of function spaces on $mathbb{R}^{n}$.

A Characterization of Riesz Potential and Its Commutator in Local Complementary Generalized Orlicz–Morrey Spaces

Journal of Function Spaces
In this paper, we find sufficient conditions on functions ω1,ω2 which ensure the boundedness of Riesz potentials and their commutators with BMO functions from one local complementary generalized Orlicz–Morrey spaces M ∁Φ,ω1x0ℝn to the spaces M ∁Ψ,ω2x0ℝn.
