The approximation of functions by singular integrals is an important question in the theory of differential and integral equations. Therefore the consideration of approximation problems in various norms is useful. Recently in many papers approximation problems have been studied in the Holder norms

Abstract
The boundedness of singular convolution operators f ↦ k ∗︁ f is studied on Besov spaces of vector‐valued functions, the kernel k taking values in ℒ︁(X , Y ). The main result is a Hörmander‐type theorem giving sufficient conditions for the boundedness of such an operator on these spaces. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

## Abstract Let __X__ = (__X__, __d__, __μ__)be a doubling metric measure space. For 0 < __α__ < 1, 1 ≤__p__, __q__ < ∞, we define semi‐norms equation image When __q__ = ∞ the usual change from integral to supremum is made in the definition. The Besov space __B~p, q~^α^__ (__X__) is the set of th
