Summary: | Based on a coupling conjugation scheme and the perturbational approach, we build Fenchel-Lagrange dual problem of a composed optimization model with infinite constraints in separated locally convex spaces. This paper has mainly two targets. One is to establish strong duality under a new regularity condition (
$ {\rm RC}_A $
RC
A
) and an extension closed-type condition (
$ {\rm ECRC}_A $
ECRC
A
). The e-convex counterpart of Fenchel-Moreau theorem plays a key role in analysing the relation between them. The other aim is to achieve the sufficient and necessary characterizations for total duality in terms of c-subdifferentials. For this purpose, a formula for ε-c-subdifferentials of a proper function composed with a linear continuous operator is proved and applied. |
