Weighted norm inequalities for pseudo-differential operators and their commutators

open access: yes, 2012
This paper is dedicated to study weighted $L^p$ inequalities for pseudo-differential operators with amplitudes and their commutators by using the new class of weights $A_p^\vc$ and the new BMO function space BMO$_\vc$ which are larger than the ...

Pointwise multipliers of weighted BMO spaces [PDF]

open access: yesProceedings of the American Mathematical Society, 1993
In a recent paper by S. Bloom (Pointwise multipliers of weighted B M O BMO spaces, Proc. Amer. Math. Soc. 105 (1989), 950-960), there are some inaccuracies. In this note, we give a counterexample to his "theorem" and a corrected form with proof under a suitable condition on weights.

Well/ill-posedness for the dissipative Navier–Stokes system in generalized Carleson measure spaces

open access: yesAdvances in Nonlinear Analysis, 2017
As an essential extension of the well known case β∈(12,1]{\beta\kern-1.0pt\in\kern-1.0pt({\frac{1}{2}},1]} to the hyper-dissipative case β∈(1,∞){\beta\kern-1.0pt\in\kern-1.0pt(1,\infty)}, this paper establishes both well-posedness and ill-posedness (not ...

Logarithmic mean oscillation on the polydisc, endpoint results for multi-parameter paraproducts, and commutators on BMO

open access: yes, 2012
We study boundedness properties of a class of multiparameter paraproducts on the dual space of the dyadic Hardy space H_d^1(T^N), the dyadic product BMO space BMO_d(T^N). For this, we introduce a notion of logarithmic mean oscillation on the polydisc. We

BMO spaces related to Laguerre semigroups

open access: yesMathematische Nachrichten, 2013
For the system of Laguerre functions we define a suitable BMO space from the atomic version of the Hardy space considered by Dziubański in , where is the maximal operator of the heat semigroup associated to that Laguerre system. We prove boundedness of over a weighted version of that BMO, and we extend such result to other systems of Laguerre ...

Global boundedness of a class of multilinear Fourier integral operators

open access: yesForum of Mathematics, Sigma, 2021
We establish the global regularity of multilinear Fourier integral operators that are associated to nonlinear wave equations on products of $L^p$ spaces by proving endpoint boundedness on suitable product spaces containing combinations of the local ...

A Weighted Variant of Riemann-Liouville Fractional Integrals on ℝn

open access: yesAbstract and Applied Analysis, 2012
We introduce certain type of weighted variant of Riemann-Liouville fractional integral on ℝn and obtain its sharp bounds on the central Morrey and λ-central BMO spaces.

UMD-valued square functions associated with Bessel operators in Hardy and BMO spaces

open access: yes, 2013
We consider Banach valued Hardy and BMO spaces in the Bessel setting. Square functions associated with Poisson semigroups for Bessel operators are defined by using fractional derivatives.

BMO- and VMO-spaces of slice hyperholomorphic functions [PDF]

open access: yesMathematische Nachrichten, 2017
In this paper we continue the study of important Banach spaces of slice hyperholomorphic functions on the quaternionic unit ball by investigating the BMO- and VMO-spaces of slice hyperholomorphic functions. We discuss in particular conformal invariance and a refined characterization of these spaces in terms of Carleson measures.
