COMMUTATORS OF FRACTIONAL INTEGRALS ON MARTINGALE MORREY SPACES

摘要

On martingale Money spaces we give necessary and sufficient conditions for the boundedness and compactness of the commutator generated by the fractional integral and a function in the martingale Campanato space. We also give the conditions for the boundedness and compactness from martingale Money spaces to martingale Triebel-Lizorkin-Morrey spaces.
