On Elliptic Problems in Besov Spaces
Mathematische Nachrichten, 1991First, some properties of Besov spaces are explained and linear elliptic problems in \(B_{p,q}^ \alpha (R^ n) \) are studied. Further, general linear boundary value problems in Besov spaces are considered. Particularly, existence and unicity of solutions are proved and sufficient conditions for the generation of semigroups by elliptic operators with ...

Multiplication properties of besov spaces
Annali di Matematica Pura ed Applicata, 1977The paper deals with the question whether f → gf (pointwise multiplication) is a bounded operator from B p,q s =B p,q s (Rn) into itself. Here B p,q s are the general (non-homogeneous isotropic ...

Morrey-Besov Spaces and Besov Capacity
2015Here, we make a brief visit to the theory of Besov spaces, Besov capacity, and the Morrey-Besov analogue of Theorem 7.1 (i) - the Sobolev inequality for the Morrey-Besov setting. In fact, we shall say that a function u(x) satisfies the Morrey-Besov condition if \(u \in L^{p}(\mathbb{R}^{n}),\;1 \leq p

Mean Oscillation and Besov Spaces
Canadian Mathematical Bulletin, 1985AbstractThe homogeneous Besov-Lipschitz spaces, usually defined by difference operators or Fourier transform, are studied in terms of mean oscillation, and several equivalent characterisations are given.

Besov Spaces and a Trace Ideal
Acta Mathematica Hungarica, 1999Let \(\Pi_2\) be the operator ideal of all absolutely 2-summing operators and let \((\Pi_2)_{2,1}^{(a)}\) be the ideal of operators whose sequences of \(\Pi_2\)-approximation numbers belong to the Lorentz sequence space \(\ell_{2,1}\). The author presents two results of the following kind. If a given matrix or kernel function belongs to a certain Besov

Rearrangements of Functions in Besov Spaces
Mathematische Nachrichten, 2001Let \(BV(0,l)\) be the space of functions of bounded variation in \((0,l)\). For \(\theta \in(0,1)\) and \(p\in[1,\infty]\) define \(Z_{\theta,p}(0,l)\) as \[ Z_{\theta,p}(0,l)= (L_\infty(0,l), BV(0,l))_{\theta,p}, \] the real interpolation space between \(L_\infty(0,l)\) and \( BV(0,l)\). The Banach space \(V_p(0,l)\) is defined by \[ V_p(0,l)=\{ u\in

Composition Semigroups on the Besov Spaces
Complex Analysis and Operator TheoryWe study semigroups of composition operators acting on the Besov spaces $B_p$, where they exhibit some new behaviors relative to many classical spaces. Often for a Banach space $X$ of analytic functions on the unit disk, the maximal closed space of strong continuity, $[ φ_t, X ]$, exists for every semigroup $\{ φ_t \}$ of analytic self-maps of the disk,
