Phelps’ Lemma, Danes’ Drop theorem and Ekeland’s principle in locally convex spaces
(2003)A generalization of Phelps' lemma to locally convex spaces is proven, applying its wellknown Banach space version. We show the equivalence of this theorem, Ekeland's principle and Danes' drop theorem in locally convex ... 
An εlagrange multiplier rule for a mathematical programming problem on Banach spaces
(2001)The aim of this paper is to extend the multiplier rule due to Clarke for a nondifferentiable mathematical programming problem on a Banach space to eminimal (suboptimal) solutions of the problem. This seems to be useful ... 
Representative Litigation in Italian Capital Markets: Italian Derivative Suits and (if ever) Securities Class Actions
(De Gruyter, 2009)In this article I investigate representative litigation in the Italian company law and financial law context. In Section I, I will analyze derivative actions, which were introduced in 1998 and which can be considered up ... 
Closing the duality gap in linear vector optimization
(2004)Using a setvalued dual cost function we give a new approach to duality theory for linear vector optimization problems. We develop the theory very close to the scalar case. Especially, in contrast to known results, we avoid ... 
The economics of art thefts: Too much screaming over Munch’s Scream?

A duality theory for setvalued functions I: Fenchel conjugation theory
(SPRINGER, 2009)It is proven that a proper closed convex function with values in the power set of a preordered, separated locally convex space is the pointwise supremum of its setvalued affine minorants. A new concept of LegendreFenchel ...
