title: Weighted inequalities for fractional integral operators and linear commutators in the Morrey-type spaces.
abstract: In this paper, we first introduce some new Morrey-type spaces containing generalized Morrey space and weighted Morrey space with two weights as special cases. Then we give the weighted strong type and weak type estimates for fractional integral operators [Formula: see text] in these new Morrey-type spaces. Furthermore, the weighted strong type estimate and endpoint estimate of linear commutators [Formula: see text] formed byband [Formula: see text] are established. Also we study related problems about two-weight, weak type inequalities for [Formula: see text] and [Formula: see text] in the Morrey-type spaces and give partial results.
