Journal of Function Spaces and Applications, 2012 We introduce the Besov-Schatten spaces 𝐵𝑝(ℓ2), a matrix version af analytic Besov space, and we compute the dual of this space showing that it coincides with the matricial Bloch space introduced previously in Popa (2007).

Nonlinear Analysis, 2020 Let $Ω$ be a smooth bounded domain in $\mathbb R^n$ and u be a measurable function on $Ω$ such that $|u(x)|=1$ almost everywhere in $Ω$. Assume that u belongs to the $B^s_{p,q}(Ω)$ Besov space. We investigate whether there exists a real-valued function $φ\in B^s_{p,q}$ such that $u=e^{iφ}$.

Қарағанды университетінің хабаршысы. Математика сериясы, 2019 In this paper, we investigate the boundedness of the norm of the convolution operator in Sobolev spaces with the dominated mixed derivative and anisotropic Nikolsky-Besov spaces.

Interpolation theorem for Nikol’skii-Besov type spaceswith mixed metric
Қарағанды университетінің хабаршысы. Математика сериясы, 2020 In this paper we study the interpolation properties of Nikol’skii-Besov spaces with a dominant mixed derivative and mixed metric with respect to anisotropic and complex interpolation methods.

Traces of Besov Spaces Revisited [PDF]
Zeitschrift für Analysis und ihre Anwendungen, 2000 For the trace of Besov spaces B^s_{p,q} onto a hyperplane, the borderline case with s = \frac {n}{p} – (n–1) and 0 < p &

Acta Mathematica Sinica, English Series, 2022 In this paper we introduce Besov-type spaces with variable smoothness and integrability. We show that these spaces are characterized by the $φ$-transforms in appropriate sequence spaces and we obtain atomic decompositions for these spaces. Moreover the Sobolev embeddings for these function spaces are obtained.

Equivalent norms of Herz-type Besov and Triebel-Lizorkin spaces
Journal of Function Spaces and Applications, 2005 In this paper the author obtains equivalent norms of Herz-type Besov and Triebel-Lizorkin spaces, which are generalizations of well-known Herz-type spaces and inhomogeneous Besov and Triebel-Lizorkin spaces.

Homogeneous Besov Spaces on Stratified Lie Groups and Their Wavelet Characterization
Journal of Function Spaces and Applications, 2012 We establish wavelet characterizations of homogeneous Besov spaces on stratified Lie groups, both in terms of continuous and discrete wavelet systems.
