Description

The international conférences "Journées Approximation" in Lille give opportunity for exchanging ideas by french, belgian and other european colleagues working on approximation theory, numerical  linear algebra and their applications. The ja2024 edition will be a two and a half day meeting in May 2024  from Wednesday 15th at 9 a.m. to Friday 17th at 2 p.m. with 40 minutes talks only by invitation.
