Extension and embedding theorems for Campanato spaces on C0,γ$C^{0,\gamma }$ domains

Abstract

AbstractWe consider Campanato spaces with exponents on domains of class in the N‐dimensional Euclidean space endowed with a natural anisotropic metric depending on . We discuss several results including the appropriate Campanato's embedding theorem and we prove that functions of those spaces can be extended to the whole of the Euclidean space without deterioration of the exponents .
