Abstract
We prove the strong type boundedness of the fractional Hardy-Littlewood maximal operator from weighted Morrey spaces \(L^{p,(\lambda _{1},\lambda _{2})}(|x|^{\beta p}\omega ^{p})\) to \(L^{q,(q(\lambda _{1}+\lambda _{2})/p-\lambda _{2},\lambda _{2})} (|x|^{\beta q}\omega ^{q})\) for \(p>1\) and \(\omega \in A(p,q)\). We also obtain the weak type estimate for \(p=1\) and \(\omega \in A(1,q)\).
