We are pleased to announce that the scientific programme of the 4th Conference on Ordered Structures and their Applications (COSA 2026) is now available online.
Taking place from September 14 to 18, 2026, at the Centre International de Rencontres Mathématiques (CIRM) in Luminy, Marseille, France, COSA 2026 will bring together researchers working on ordered structures, Riesz spaces, vector lattices, Banach lattices, and their applications to mathematical finance, actuarial science, economics, and data science.
📅 A rich scientific programme
The programme features a diverse series of lectures and presentations throughout the five days of the conference. It brings together internationally recognized researchers as well as emerging researchers and PhD students, offering a stimulating environment for scientific exchange and collaboration.
Among the topics addressed are:
- Ordered and Banach lattice structures
- Riesz spaces and vector lattices
- Positive operators and operator theory
- Mathematical and financial mathematics
- Portfolio optimization
- Financial markets and transaction costs
- Mean field games
- Actuarial and insurance mathematics
- Finitely additive measures
- Applications of ordered structures to contemporary mathematical problems
The programme is designed to highlight the connections between abstract ordered structures and their applications, with a particular focus on finance, actuarial science, and mathematical finance.
🌍 Five days of mathematics and collaboration
From the opening session on Monday, September 14, to the closing session on Friday, September 18, participants will have the opportunity to attend lectures, exchange ideas, and develop new scientific collaborations.
The conference will also include informal moments for discussion and networking, as well as an excursion during the week, taking advantage of the exceptional setting of CIRM in Luminy.
