Tangential Extremal Principles for Finite and Infinite Systems of Sets,   II: Applications to Semi-infinite and Multiobjective Optimization
  This paper contains selected applications of the new tangential extremal principles and related results developed in Part I to calculus rules for infinite intersections of sets and optimality conditions for problems of semi-infinite programming and multiobjective optimization with countable constraints
