fi = inf( p(x) : g(x) E 4, x E R 1, P) where S is an arbitrary convex cone in a finite dimensional space, R is a convex set, and p and g are respectively convex and S-convex (on a), were given in [lo]. These characterizations hold without any constraint qualification. They use the “minimal cone” .S’ of (P) and the cone of directions of constancy D;(S’). In the faithfully convex case these cones...
