We generalize the extrapolation theorem from Ap weights to A weights on the setting of weighted Morrey spaces by using the Rubio de Francia algorithm and ideas in a paper by D. Cruz-Uribe et al. First we have proved the classical Hardy-Littlewood maximal operator is bounded on the weighted Morrey spaces if the weight w(x) is in A and then we have obtained inequalities involving the maximal operator, vector-valued maximal operator, the sharp maximal operator, and A weights.
