ABSTRACT
We introduce 2-microlocal Besov and Triebel-Lizorkin spaces with variable integrability and give a characterization by local means. These spaces cover spaces of variable exponent, spaces of variable smoothness and weighted spaces that have been studied in recent years.
Key words: Besov spaces, Triebel-Lizorkin spaces, 2-microlocal spaces, variable
smoothness, variable integrability, local means.
