Duality theorems and optimality conditions for nonconvex optimization problems
R. Deumlich, Karl‐Heinz Elster · Mathematische Operationsforschung und Statistik Series Optimization · 1980
Continuing former papers of the authors the present paper gives assertions about φ-conjugate in connection with duality theorems and optimality conditions for a rather broad class of nonconex optimization problems. A geometrical interpretation of the statements follows in a natural way by the projective extension of the Euclideanspace.
