We are interested in proving optimality conditions for optimization problems. By means of different second-order tangent sets, various second-order necessary optimality conditions are obtained for both scalar and vector optimization problems where the feasible region is given as a set. We present also second-order sufficient optimality conditions so that there is only a very small gap with the necessary optimality conditions. As an application we establish second-order optimality conditions of Fritz John type, Kuhn-Tucker type 1, and Kuhn-Tucker type 2 for a problem with both inequality and equality constraints and a twice differentiable functions. At the end, a very general second-order necessary conditions for efficiency with respect to cones is present and it is applied to smooth and nonsmooth data.
