Atomic, molecular and wavelet decomposition of generalized 2-microlocal Besov spaces
Journal of Function Spaces and Applications, 2010 We introduce generalized 2-microlocal Besov spaces and give characterizations in decomposition spaces by atoms, molecules and wavelets. We apply the wavelet decomposition to prove that the 2-microlocal spaces are invariant under the action of ...

Electronic Journal of Differential Equations, 2018 The purpose of this article is to establish the molecular decomposition of the homogeneous Besov-Morrey spaces associated with the Hermite operator $\mathbb{H} = -\Delta+|x|^2$ on the Euclidean space $\mathbb{R}^n$.

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 ...

Well-posedness of degenerate integro-differential equations in function spaces
Electronic Journal of Differential Equations, 2018 We use operator-valued Fourier multipliers to obtain characterizations for well-posedness of a large class of degenerate integro-differential equations of second order in time in Banach spaces.

Average Widths and Optimal Recovery of Multivariate Besov Classes in Orlicz Spaces
MathematicsIn this paper, we study the average Kolmogorov σ–widths and the average linear σ–widths of multivariate isotropic and anisotropic Besov classes in Orlicz spaces and give the weak asymptotic estimates of these two widths.

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2014 In this paper we introduce the symmetric Besov-Bessel spaces. Next, we give a Sonine formula for generalized Bessel functions. Finally, we give a characterization of these spaces using the Bochner-Riesz means.

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)].
