The main focus is on commutators and maximal commutators on generalized Orlicz spaces (also known as Musielak-Orlicz spaces) for fractional maximal functions and Riesz potentials. We prove their boundedness between generalized Orlicz spaces and give a characterization for functions of bounded mean oscillation.", keywords = "maximal operator, commutator, fractional operator, generalized Orlicz, Musielak-Orlicz", issn = "1232-9274" }
