On Continuity of Inter-Section SymbolbB@ s Operation and Generic Stability of Coincident Point

Abstract:A family-of-set space was established,and its common elements’ generic stability was studied. The upper semi-continuity of operation of sets’ intersection in family-of-closed-set space was obtained,and the generic stability of coincident pointis was studied.
