In Nash bargaining problem, due to fairness concerns of players, instead of maximizing the sum of utilities of all players, an implementable solution should satisfy some axioms or characterizations. Such a solution can result in the so-called price of fairness, because of the reduction in the...

When dealing with location problems we are usually given a set of existing facilities and we are looking for the location of one or several new facilities. In the classical approaches weights are assigned to existing facilities expressing the importance of the new facilities for the existing...

The presented TEM-model describes the economical interaction between several actors (players) which intend to minimize their emissions (E <Subscript>i</Subscript>) caused by technologies (T <Subscript>i</Subscript>) by means of expenditures of money (M <Subscript>i</Subscript>) or financial means, respectively. The index stands for the i-th player, i=1, … ,n....</subscript></subscript></subscript>

Following a few words on multifunctions in the mathematical literature, a very brief recall on dual spaces, some preliminary notations and definitions in the introduction, we give some results on those functions in the second paragraph. In the third paragraph, a duality theory in...
