We study variable exponent Campanato spaces on spaces of homogeneous type. We prove an embedding result between variable exponent Campanato spaces. We also prove that these spaces are equivalent, up to norms, to variable exponent Morrey spacesLp(·),λ(·)(X) with λ+< 1 and variable exponent Hölder spacesHα(·)(X) with λ−> 1. In the setting of an arbitrary quasimetric measure spaces, we introduce the log-Hölder condition forp(x) with the distanced(x,y) replaced byμB(x,d(x,y)), which provides a weaker restriction onp(x) in the general setting and show that some basic facts for variable exponent Lebesgue spaces hold without the assumption thatXis homogeneous or even Ahlfors lower or upper regular. However, the main results for Campanato spaces are proved in the setting of homogeneous spacesX. Bibliography: 34 titles.
