Title Orally transmitted mathematics
Author CHEMILLIER Marc
Keywords Asymmetric rhythms, Cognition, Divination, Ethnomathematics, Musical canon, Sand drawing
Topics Anthropology - Ethnology, Discrete Mathematics, Drawing, Music
Abstract Ethnomathematics is a new domain studying mathematical structures in particular activities of traditional societies. The main difficulty in this approach is to establish a link between formal structures, studied « in laboratory », and mental representations of native people, as they can be observed during fieldworks. We describe these difficulties in different situations: visual arts, music, divination. In the latter case, we present the results of fieldworks done in Madagascar where mathematical mental representations of native people have been discovered

Title Is the evolution of jazz described by a log periodic law?
Author BRISSAUD Ivan
Keywords Fractals, Jazz, Log periodicity law, Temporal tree structure
Topics Fractal, Modelling, Music, Time Series, Trees
Abstract The evolution of different phenomena in biology, society, economy, human development. can be described by series of cycles and leaps. Many authors adjust a log periodic behavior to these chronologies. Here, we suggest applying such a model to the Jazz steps (Archaic Jazz, New Orleans, Jazz Hot, Swing.). In this case we show an acceleration of the cycles up to a critical time at the middle of the fifties (so called "Cool Jazz" epoch) before a deceleration corresponding to an increasing influence of African, South American. musics over the Jazz. We find a significant agreement between the model and the data. In conclusion a question remains: is a chronology of historical evolution predictable?

Title Mathematics and literature: an article with some mathematics and literature
Author AUDIN Michèle
Keywords Aragon, Arnault Daniel, Chess board, Constraint, Group, Latin square, Magic square, Oulipo, Perec Georges, Queneau Raymond, Roubaud Jacques, Sextine
