On October 27, 2023, the next meeting of the Belgian-Dutch Algebraic Geometry seminar will be held at Leiden University. Location: room EM1.09 in the Gorlaeus Building; enter through the Oort building on Niels Bohrweg (just south of the SRON Netherlands Institute for Space Research). Precise entrance location.
Note: participation is free (including an informal dinner after the talks); but for practical reasons we ask that you register, no later than October 24, via this link. Thank you!
