impanga 2023/24

IMPANGA is an algebraic geometry seminar organized by Piotr Achinger, Jarosław Buczyński, and Michał Kapustka. In the academic year 2023/24, the seminar meets twice per month for a one day session on Friday, with two 60 min talks separated by a lunch break (11:00-12:00 and 13:30-14:30). IMPANGA meets in Room 403 at IMPAN (unless stated otherwise).

To receive notifications about upcoming seminars join impanga-mailing-list@impan.pl using google account, or contact one of the organizers.

IMPANGA was founded at IMPAN in 2000 by late Piotr Pragacz. See here for information on former meetings of IMPANGA
