Abstract: In this paper, we study a boundedness property of the Adams type for multilinear fractional integral operators with the multilinear $L^{r^{\prime},\alpha}$-Hörmander condition and their commutators with vector valued BMO functions on a Morrey space and a predual Morrey space. Moreover, we give an endpoint estimate for multilinear fractional integral operators. As an application, we obtain the boundedness of multilinear Fourier multipliers with limited Sobolev regularity on a Morrey space.

Key words: Multilinear fractional integral, $L^{r^{\prime},\alpha}$-Hörmander condition, commutators, BMO spaces, Morrey spaces, multilinear Fourier multiplier
