On the equivalence of the K-functional and the modulus of continuity on the Morrey spaces
In this note, the Morrey spaces and the Sobolev–Morrey spaces are considered. In particular, the K-functional with respect to these spaces is estimated from above and below. As an application, we characterize the Nikol'skii–Besov–Morrey spaces via real interpolation. © 2019 Elsevier Inc.
