In this paper, we restudied the two-weight problem of multilinear fractional maximal operator Mα. First, we gave a characterization of two-weight inequalities for Mα related to a multilinear analogue of Sawyer’s two-weight condition , which essentially improved and extended some known results before. This was done mainly by using the technique of the well known atomic decomposition of tent space. Then we obtained the strong boundedness of Mα associated with multiple weight class, which removed the power bump condition assumed in the known results before. Finally, a new two-weight condition was introduced and the two-weight inequality of Mα with condition was established.
