The related weak type inequality is also obtained. The derived results are used to get appropriate boundedness of $T_γ,μ$ in Morrey spaces defined with respect to a measure $μ$.enMultilinear fractional integralsSpaces defined with respect to measureQuasi-metric measure spacesMorrey spacesjournal-article10.1007/s12220-019-00159-6
