Abstract cone approximations and generalized differentiability in nonsmooth optimization
Karl‐Heinz Elster, Jörg Thierfelder · Optimization · 1988
In the present paper a connection between cone approximations of sets and generalized differentiability notions will be given. Using both conceptions we present an approach to derive necessary optimality conditions for optimization problems with inequality constraints. Moreover, several constraint qualifications are proposed to get Kuhn-Tucker-type-conditions.
