Query: Generalized fractional integral operators and their commutators with
  functions in generalized Campanato spaces on Orlicz spaces   We investigate the commutators $[b,I_{\rho}]$ of generalized fractional
integral operators $I_{\rho}$ with functions $b$ in generalized Campanato
spaces and give a necessary and sufficient condition for the boundedness of the
commutators on Orlicz spaces. To do this we define Orlicz spaces with
generalized Young functions and prove the boundedness of generalized fractional
maximal operators on the Orlicz spaces.
