IMPANGA is an algebraic geometry seminar created at IMPAN in 2000 by Piotr Pragacz. It is currently organized by Piotr Achinger, Jarosław Buczyński, and Michał Kapustka, with Piotr Pragacz as Honorary Chairman.

In the academic year 2021/22, IMPANGA meets twice per month for a one day session on Friday, with two 60 min talks separated by a lunch break:

I. 10:30-11:30
II. 12:50-13:50

The seminar meets in Room 321 at IMPAN (unless stated otherwise). Occasionally, the seminar takes place online (on Zoom), in which case the break is shortened to 15 min (10:30-11:30 and 11:45-12:45). Please email one of the organizers for the Zoom link.
