| Abstract: | It is studied how to get a global minimum of a function over a sphere.A differential equation is introduced to construct canonical dual function.The corresponding perfect duality theory is established to show the relationship between the KKT points of the primal problem and the canonical dual problem.A new definition on canonical convex multiplier is given with a canonical dual method for the primal problem.Some examples are illustrated. |
