【Abstract】 It is proved that the Pareto optimal point exists on any weak bounded closed set in an ordered locally convex space with the closed cone with π property and on any bounded closed set in an ordered complete locally convex space with the closed angle cone or closed cone with π property. Meanwhile, a satisfying result uncovering the dual property of the angle cone and the cone with π property is given.更多还原
