Multiobjective Lagrangian duality for portfolio optimization with risk measures

Pagani, Elisa - Dipartimento di Scienze Economiche, Facoltà di Economia - 2010

multidimensional case without exploiting any scalarization technique of the random vector. We refer to the approach of the image space … analysis in order to recall weak and strong Lagrangian duality results obtained through separation arguments. Finally, we …

On Lagrangian Duality in Vector Optimization. Applications to the linear case.

Pagani, Elisa - Dipartimento di Scienze Economiche, Facoltà di Economia - 2009

The paper deals with vector constrained extremum problems. A separation scheme is recalled; starting from it, a vector Lagrangian duality theory is developed. The linear duality due to Isermann can be embedded in this separation approach. Some classical applications are extended to the...
