Boundedness of fractional maximal operator and its commutators on generalized Orlicz-Morrey spaces

Vagif S. Guliyev, Fatih Deringoz

We consider generalized Orlicz-Morrey spaces $M_{\Phi ,\phi }({\mathbb{R}}^n)$ including their weak versions $W{M}_{\Phi ,\phi }({\mathbb{R}}^n)$. We find the sufficient conditions on the pairs $(φ_…
