AbstractA generalized induction theorem and some general open mapping theorems for multifunctions are straightforwardly proved based on a unique convergence procedure. Many well-known open mapping theorems, closed graph theorems, theorems of the Lusternik type, and results on approximation and semicontinuity or their refinements are obtained as consequences
