Detailed scientific programme | LECTURES
The registration and welcome reception starts already on Sunday June 28, 2026 at 6 pm at the conference venue. We recommend all participants to register already on Sunday evening. If needed, the registration will be open also on Monday morning and throught the whole conference.
The conference opens on Monday June 29 at 9 am and closes by Friday’s lunch. For more details, see the programme overview.
The preliminary time schedule of minisyposia is already available.
Equadiff 2026 highlights
- The conference features three thematic sections: Ordinary Differential Equations, Partial Differential Equations, and Numerical Analysis.
