We modify the Hotelling model to introduce the possibility that insufficiently differentiated but not necessarily identical products may induce buyers to be price-oriented. Price-oriented buyers purchase the cheapest good independently of its charact

Given a partial order Q , its semiorder dimension is the smallest number of semiorders whose intersection is Q . When we look at the class of partial orders of fixed semiorder dimension k , no characterization is known, even in the case k = 2 . In th

The niche graph of a digraph D is the (simple undirected) graph which has the same vertex set as D and has an edge between two distinct vertices x and y if and only if N+D(x) ∩ N+D(y) ≠ ∅ or N−D(x) ∩ N−D(y) ≠ ∅, where N+D(x) (resp. N

It is an open question to give a combinatorial interpretation of the Falk invariant of a hyperplane arrangement, i.e. the third rank of successive quotients in the lower central series of the fundamental group of the arrangement. In this article, we

During the last decades, an important number of Multicriteria Decision Aid Methods (MCDA) has been proposed to help the decision maker to select the best compromise alternative. Meanwhile, the PROMETHEE (Preference Ranking Organization Method for Enr

We present a model of electoral competition with endogenous platforms and campaign spending where the division of voters between impressionable and ideological is also endogenous and depends on parties’ strategic platform choices. Our approach resu

Necessary and sufficient conditions under which semiorders on uncountable sets can be represented by a real-valued function and a constant threshold are known. We show that the proof strategy that we used for constructing representations in the case
