【Abstract】 The author prove that there exists a non-empty closed convex set A in infinite Banach space with schauder base, int A=φ and A isn′t a Co-Supported set, and pose some new problems. Which problems are related with theory of function analysis, conver analysis, optinization and coplementary problem.更多还原
