This paper presents a method for defining a consistent market through the interpretation of different agents´ opinions. We suppose that every agent has his own opinion about the other agents being his possible competitors or not. These opinions are ex-ante defined and therefore (for a...

We have investigated the detailed field and temperature dependence of the dielectric constant, electric polarization, magnetization and magnetostriction in orthorhombic HoMn<Subscript>2</Subscript>O<Subscript>5</Subscript> single crystals. HoMn<Subscript>2</Subscript>O<Subscript>5</Subscript> displays incommensurate antiferromagnetic ordering below 39 K, becoming commensurate on...</subscript></subscript></subscript></subscript>

In the present paper we consider a situation in which the individual preferences and the social preference relation are intuitionistic fuzzy and study the compatibility between the Pareto principle and Sen’s minimal liberalism condition. A possible factorization of the intuitionistic fuzzy...

We consider the class of proper monotonic simple games and study coalition formation when an exogenous weight vector and a solution concept are combined to guide the distribution of power within winning coalitions. These distributions induce players' preferences over coalitions in a hedonic...

We study group formation by heterogeneous players when players’ preferences are dictated by status-seeking. Status can be intrinsic or associative. Considering these two types of status as either complements or substitutes results in non-emptiness of the core of the corresponding games and...
