The objective of this workshop is to study the patrimonialization of mathematics according to three complementary issues, in which quantitative analyses and case-based approaches are combined: 1° patrimonial dynamics and communities; 2° patrimonialization by selection and accumulation: supports, places and actors; 3° patrimonial legitimization and memory of mathematics. It will thus reinforce the understanding of the processes and modalities of the preservation and dissemination of mathematics in the long term, while proposing a methodological reflection on the articulation of the quantitative and qualitative points of view in the history of mathematics.
