The paper introduces qualification conditions for multivalued functions in Banach spaces involving the A-approximate subdifferential, and it shows that these conditions guarantee metric regularity of multivalued functions. The results are then applied for deriving Lagrange multipliers of Fritz-John type and Kuhn-Tucker type for infinite non-smooth vector optimization problems.
