-2- Chronology, ceramics and statistics, in collaboration with S. Dabo, X. Deru, G. Florent, SFECAG, French Society for the Study of Ancient Ceramics in Gaul, Proceedings of the Congress of Langres, 2007, p. 49-60.
We use an axiom of archaeological excavation 'the same is contemporary', according to which: two sets of identical furniture are contemporary to find the ordered dating of ceramic fragments from descriptive statistics methods. The arrow of time is reproduced thanks to the similarity step by step. The results cross other methods used (dendrochrono-logical, radiocarbon, archaeomagnetic) and this confirmed the relevance of the axiomatic approach.
-4- Demonstration of a ceramic facies in the north-west of Roman Belgium, in collaboration with Xavier Deru and Moez Kilani, SFECAG, French Society for the Study of Antique Ceramics in Gaul, Proceedings of the congress of Chelles, 2010 , p. 207-224. Written in collaboration with X. Deru, and Mr. Kilani.
This paper provides an interpretation in terms of spatial competition to the mapping of some ceramic facies examined in archeology. He shows that the circular location model of the production workshops provides an explanation consistent with the spatial arrangement, or what archaeologists call the right-of-way, of these facies. This economic model gives a better account of the data and makes it possible to abandon certain competing explanatory hypotheses: respectively the culturalist hypothesis, the identity hypothesis or the ethnic hypothesis.
