摘　　要：The aim of this paper is to establish the boundedness of bilinear pseudodifferential operator T_(σ) and its commutator[b_(1),b_(2),T_(σ)]generated by T_(σ) and b_(1),b_(2) BMO(R^(n))on generalized fractional weighted Morrey spaces L^(p,η,φ)(w).Under assumption that a weight satisfies a certain condition,the authors prove that Ts is bounded from products of spaces L^(p1,η1,φ)(w1)L^(p2,η2,φ)(w2)into spaces L^(p,η,φ)(w),where w=(w_(1),w_(2)) A_(P),P=(p1,p2),η=η1+η2 and 1/p=1/p_(1)+1/p_(2) with p_(1),p_(2)(1,∞).Furthermore,the authors show that the[b1,b2,T_(σ)]is bounded from products of generalized fractional Morrey spaces L^(p1,η1,φ)(R^(n))L^(p2,η2,φ)(R^(n))into L^(p,η,φ)(R^(n)).As corollaries,the boundedness of the T_(σ) and[b_(1),b_(2),T_(σ)]on generalized weighted Morrey spaces L^(p,φ)(w)and on generalized Morrey spaces L^(p,φ)(R^(n))is also obtained.
