Some scientiﬁc achievements

In the study of ranges, the first example of a finitely additive measure that does not enjoy the Liapounoff Property of the range has been given in [1]; the same example is suitable also to prove several other pathologies of the finitely additive case (see [29]). The investigation of countably additive restrictions also includes the proof of the important Hered- 2 itarily Overlapping Boundary Property (H.O.B.P.) [8], a geometric property of the ranges of R - valued strongly non-atomic measures (both finitely and countably additive). By virtue of the H.O.B.P. the first finitely additive Radon-Nikodym Theorem has been obtained in [14] besides the new results concerning proximinal subspaces of C(K) ([27]). For what concerns Vector integration, it could be said that A. M. jointly with other authors has given a wide range of results: for instance in [23] the best way to define vector integration in a Choquet sense is given. The systematic study of Radon-Nikodym Property for finitely additive measures has stemmed from the first interesting characterization of an exact Radon-Nikodym Theorem for a pair of non-negative finitely additive measures µ and ν: If µ ν and they are both strongly non atomic, dµ then exists iff the range of the pair (µ, ν) contains all its exposed points. dν A. M. and Anna Rita Sambucini have been the first authors that faced the finitely additive version of multivalued integration, and their main contributions are the geometric and topological properties of multivalued integrals of Banach valued correspondences in several dfferent settings, some of special interest towards applications in Equilibrium Theory ([32]).

3 Among the minimax results that have been obtained jointly with Anna Salvadori in the late eighties, the vector version of the Hahn-Banach Theorem obtained in [9] is worth of mention. A. M. has also given some contributions in different fields of Functional Analysis; among them we mention the elegant characterization of proximinality for a subspace V of finite codimension in C(K), which enables to check its proximinality by means of only finitely many elements in the annihilator of V [27], and the completely new point of view of [30] and [33] in defining the Drop Property by means of different classes of ‘small’ sets in a Banach space. General Equilibrium Theory is an important branch of Mathematical Economics. In a series of recent papers the core-walras equivalence has been given for very general models of economies: finitely additive economies, with infinite-dimensional commodity space in the (unusual in the finitely additive setting) individualistic approach; they are therefore suitable for modelling economies in infinite time horizon, without restrictions in the mechanism of coalition forming. They represent also an increasing line of generalizations of the milestone paper by Rustichini and Yannelis.
