Local Characterizations of Besov and Triebel-Lizorkin Spaces with Variable Exponent

open access: yesJournal of Function Spaces, 2014
We introduce new Besov and Triebel-Lizorkin spaces with variable integrable exponent, which are different from those introduced by the second author early.

Boundedness of Generalized Parametric Marcinkiewicz Integrals Associated to Surfaces

open access: yesMathematics, 2019
In this article, the boundedness of the generalized parametric Marcinkiewicz integral operators M Ω , ϕ , h , ρ ( r ) is considered. Under the condition that Ω is a function in L q ( S n - 1 ) with q &

Continuous Characterizations of Besov-Lizorkin-Triebel Spaces and New Interpretations as Coorbits

open access: yesJournal of Function Spaces and Applications, 2012
We give characterizations for homogeneous and inhomogeneous Besov-Lizorkin-Triebel spaces (H. Triebel 1983, 1992, and 2006) in terms of continuous local means for the full range of parameters.

Traces of Besov, Triebel-Lizorkin and Sobolev Spaces on Metric Spaces

open access: yesAnalysis and Geometry in Metric Spaces, 2017
We establish trace theorems for function spaces defined on general Ahlfors regular metric spaces Z. The results cover the Triebel-Lizorkin spaces and the Besov spaces for smoothness indices s < 1, as well as the first order Hajłasz-Sobolev space M1,p(Z).

Littlewood, Paley and almost‐orthogonality: a theory well ahead of its time

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract The classic paper by Littlewood and Paley [J. Lond. Math. Soc. (1), 6 (1931), 230–233] marked the birth of Littlewood–Paley theory. We discuss this paper and its impact from a historical perspective, include an outline of the results in the paper and their subsequent significance in relation to developments over the last century, and set them ...

Generalized quasi‐geostrophic equation in critical Lorentz–Besov spaces, based on maximal regularity

open access: yesMathematische Nachrichten, Volume 299, Issue 3, Page 637-660, March 2026.
Abstract We consider the quasi‐geostrophic equation with its principal part (−Δ)α${(-\mathrm{\Delta})^{\alpha}}$ for α>1/2$\alpha >1/2$ in Rn$\mathbb {R}^n$ with n≥2$n \ge 2$. We show that for every initial data θ0∈Ḃr,q1−2α+nr$\theta _0 \in \dot{B}^{1-2\alpha + \frac{n}{r}}_{r, q}$ with 1
