Around Jean-Pierre Barthélemy's works Language   French Read the article Title Order structures and social sciences Author LECLERC Bruno, MONJARDET Bernard Keywords Formel concept analysis, Galois lattice, Guttman scale, Lattice, Majority, Médiane, Order Topic None Abstract We present two frequent uses of order structures in Social Sciences. The first one addresses what is often called Formal Concept Analysis, particularly used in data analysis and data mining. The second concerns the "median procedure" present in social choice as well as in mathematical taxonomy. At the origins of each of these uses, one finds innovative results due to Marc Barbut. In the first case, about Guttman scales in hierarchic analysis and about Galois lattices, in the second, about relations between medians and Condorcet's majority rule.

Equivalently, it admits no subgraph of which every vertex has degree at least three, and is maximal with this property, for a fixed number of vertices. It is known that a tree distance may be summarized by 2n-3 of its entries, conveniently chosen. Arch graphs with n vertices correspond to such sets of entries. They include the graphs of the so-called 2-tree type. We study these graphs, and the k-arch graphs and k-trees which naturally generalize them. It is recalled how a tree metric or function is associated to a valued arch graph, and the properties of this correspondence are investigated.
