On December 11, 2026, the next meeting of the Belgian-Dutch Algebraic Geometry seminar will be held at the University of Antwerp.
All talks will take place in the Stadscampus S.C.002, around 15 minutes on foot from Antwerpen Central station. Here is a map. The building can be accessed via Prinsstraat, or via the s.E building where the Agora Cafe is.
