%0 Journal Article %T Some Estimates of Rough Bilinear Fractional Integral %A Yun Fan %A Guilian Gao %J Journal of Function Spaces and Applications %D 2012 %I Hindawi Publishing Corporation %R 10.1155/2012/406540 %X We study the boundedness of rough bilinear fractional integral on Morrey spaces and modified Morrey spaces and obtain some sufficient and necessary conditions on the parameters. Furthermore, we consider the boundedness of on generalized central Morrey space . These extend some known results. %U http://www.hindawi.com/journals/jfsa/2012/406540/
