Besov spaces, Sobolev spaces, and Cauchy integrals.

Michigan Mathematical Journal, 1992
Si \(B_ n\) désigne la boule unité de \(\mathbb{C}^ n\) de frontière \(S\), les auteurs mettent en évidence des conditions suffisantes sur \(f\in L^ 1(S)\) pour que l'application \[ Sf: z\in B_ n \to Sf(z)=\int_ S f(\zeta) {{d\sigma(\zeta)} \over {(1-\langle z,\zeta\rangle)^ n}} \] appartienne soit à l'espace de Besov \(B_ \beta^ p\) soit à l'espace de

Characterization of nonlinear Besov spaces

Transactions of the American Mathematical Society, 2019
The canonical generalizations of two classical norms on Besov spaces are shown to be equivalent even in the case of nonlinear Besov spaces, that is, function spaces consisting of functions taking values in a metric space and equipped with some Besov-type topology.

Oscillating singularities in Besov spaces

Journal de Mathématiques Pures et Appliquées, 2004
The purpose of multifractal analysis is to evaluate the Hausdorff dimensions d(h) of the sets Sh of points where the pointwise Hölder exponent of a function, a signal or an image has a given value h∈[h0,h1]. Inside the realm of mathematics this makes good sense but for most signals or images such calculations are out of reach.

Wavelets on fractals and besov spaces

The Journal of Fourier Analysis and Applications, 1998
The author develops the theory of wavelets on self-similar fractals \(K\) which preserves a certain standard inequality (Markov's inequality). This property is equivalent to the statement that for all balls \(B\) centered at a point in \(K\), and all polynomials \(P\) of degree at most \(m\), one has \[ \sup_{x \in B} | P(x)| \leq C_m \sup_{x \in B ...

Characterizations of Bloch space and Besov spaces by oscillations

Hokkaido Mathematical Journal, 2000
Some new oscillation characteristics of analytic Bloch and Besov spaces in the disk are given. The results extend and generalize the earlier work by \textit{K. Zhu}, see p. 328 in [J. Math. Anal. Appl. 157, No. 2, 318-336 (1991; Zbl 0733.30026)].

Homogeneous Besov Spaces in Dunkl Setting

Potential Analysis
The purpose of this paper is to characterize the homogeneous Besov space in the Dunkl setting. We utilize a new discrete reproducing formula, that is, the building blocks are differences of the Dunkl-Poisson kernel which involves both the Euclidean metric and the Dunkl metric.
