In the present paper, we shall give a necessary and sufficient condition for the weak/strong boundedness of generalized fractional maximal operators on generalized Orlicz–Morrey spaces. We also give necessary and sufficient conditions for the vector-valued inequalities of the Hardy–Littlewood maximal operator, generalized fractional maximal operators and singular integral operators on these function spaces. Keywords Generalized fractional maximal operators Generalized Orlicz–Morrey spaces Hardy–Littlewood maximal operator Singular integral operators Vector-valued inequalities
