4th Conference on Ordered Structures and their Applications
With a Special Focus on Applications to Finance, Actuarial Science and Mathematical Finance
September 14–18, 2026 – CIRM, Marseille, France
We are pleased to announce that the 4th edition of the Conference on Ordered Structures and their Applications (COSA) will take place at the CIRM, a world-class research center located in Marseille, France, from September 14 to 18, 2026.
In this edition, COSA conference brings together researchers working on Mathematical Finance with specialists working on Riesz spaces, vector lattices, ordered algebraic structures, and their applications in mathematical finance, economics, and data science
🌍 A Journey from South to North
COSA began as a virtual event during the pandemic and has since evolved into a traveling conference, with past editions held in Tozeur (Tunisia), Kenitra (Morocco), and the Wits Rural Facility (South Africa).
This 2026 edition marks a symbolic scientific milestone: an initiative born in Africa now hosted at one of Europe’s most prestigious mathematical centers. It highlights the growing international recognition of African scientific communities, despite persistent structural challenges.
