【Abstract】 A class of functions called B-preinvex functions are discussed in this paper.some other properties of B-preinvex functions are established and a sufficient condition of B-preinvex functions is also obtained.Furthermore the sufficient optimality conditions and duality results are obtained for a nonlinear programming problem involving B-preinvex functions.更多还原
