NUCLEAR CONES IN PRODUCT SPACES, PARETO EFFICIENCY AND EKELAND-TYPE VARIATIONAL PRINCIPLES IN LOCALLY CONVEX SPACES

摘要

In this article, we present a method to obtain new Ekeland-type variational principles for mappings defined between locally convex spaces. The method is based on a special nuclear cone defined in a product of two locally convex spaces and on Pareto efficiency with respect to this cone.
