Hypergraphe
modifierBonjour.
In the article Hypergraphe, you wrote that the term Hypergraph was introduced by Claude Berge in 1960. I really need a reference to the source. Or at least to any article that was published before 1967, in which this term was used.

- Hello
- I am still looking for a reference. This sentence was taken from a website now down. Actually, I think the sentence is incorrect and a correct sentence would by "dans les années 60" or "in the sixties". Koko90 (discuter) 29 août 2013 à 16:28 (CEST)
- PS: I think the error came from a bad interpretation of the introduction of the books Hypergraphs by Berge:
For the past forty years, Graph Theory has proved to be an extremely useful tool for solving combinatorial problems, in areas as diverse as Geometry, Algebra, Number Theory, Topology, Operations Research and Optimization. It was thus natural to try and generalise the concept of a graph, in order to attack additional combinatorial problems. The idea of looking at a family of sets from this standpoint took shape around 1060. In regarding each set as a "generalised edge" and in calling the family itself a "hypergraph", the initial idea was to try to extend certain classical results of Graph Theory such as the theorems of Turcin and Kgnig. Next, it was noticed that this gen- eralisation often led to simplification; moreover, one single statement, sometimes remarkably simple, could unify several theorems on graphs. It is with this motiva- tion that we have tried in this book to present what has seemed to us to be the most significant work on hypergraphs.
