Abstract: We present a survey on optimality conditions (of Fritz-John and KKT- type) for semi-infinite convex optimization problems. The methodology is based on the use of the subdifferential of the supremum of the infinite family of constraint functions. Our approach aims to establish weak constraint qualifications and, in the last step, to drop out the usual continuity/closedness assumptions which are standard in the literature. The material in this survey is extracted from the following papers:
