, 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

Pointwise multipliers of weighted BMO spaces [PDF]
Proceedings 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.

Global boundedness of a class of multilinear Fourier integral operators
Forum 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 ...

Spaces H^1 and BMO on ax+b-groups
, 2008 Let S be the semidirect product of R^d and R^+ endowed with the Riemannian symmetric space metric and the right Haar measure: this is a Lie group of exponential growth. In this paper we define an Hardy space H^1 and a BMO space in this context.

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

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

Logarithmically Improved Regularity Criteria for a Fluid System with the Linear Soret Effect
Abstract and Applied Analysis, 2012 We consider the 3D fluid system with the linear Soret effect. We obtain a logarithmically improved regularity criterion in the BMO space.

Pointwise multipliers of weighted BMO spaces [PDF]
Proceedings of the American Mathematical Society, 1989 Let \(w:{\mathbb{R}}\to {\mathbb{R}}^+\) be a weight function satisfying the doubling condition: \(\int_{J}w(x)dx\leq C\int_{I}w(x)dx\), whenever I and J are intervals such that \(I\subset J\) and \(| J| \leq 2| I|\). The paper under review describes the weighted atomic \(H^ 1\)- space \(H_ w^ 1({\mathbb{R}})\) and weighted BMO-space \(BMO_ w({\mathbb ...

A Weighted Variant of Riemann-Liouville Fractional Integrals on ℝn
Abstract 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.

Bank Opacity and Safe Asset Moneyness
Journal of Money, Credit and Banking, EarlyView.Abstract A bank is more effective as a supplier of money‐like safe assets when (i) its return on equity (ROE) is relatively lower and (ii) it is relatively more opaque about its balance sheet. A model is presented to support this, emphasizing that safe asset investors focus on the left tail of the collateral value distribution.
