Maximal function and generalized fractional integral operators on the weighted Orlicz-Lorentz-Morrey spaces

We define the weighted Orlicz-Lorentz-Morrey and weak weighted Orlicz-Lorentz-Morrey spaces to generalize the Orlicz spaces, the weighted Lorentz spaces, the Orlicz-Lorentz spaces, and the Orlicz-Morrey spaces. Furthermore, necessary and sufficient conditions for the boundedness of the Hardy-Littlewood maximal operator, generalized fractional integral, and maximal operators on the weighted Orlicz-Lorentz-Morrey and weak Orlicz-Lorentz-Morrey spaces are given, based on the exploration of properties of Young functions, B p {B}_{p} weights, and B p , infinity {B}_{p,\infty } weights. Specifying the weights and the Young functions, we recover the existing results and we obtain new results in the new and old settings.
