Workshop on Prismatic Cohomology
We will study prismatic cohomology, a new cohomology theory developed by Bhargav Bhatt and Peter Scholze. There will be 10 talks, see below for further details.
Date: March 27 – 29, 2019 (We will start on Wednesday at 10am, and the workshop will end on Friday around 2pm)
Place: Department of Mathematics, University of Duisburg-Essen (Thea-Leymann-Str. 9, 45127 Essen)
If you are interested in attending, please send an email to Ulrich Görtz, firstname.lastname@example.org, so that we can keep track of how many people will be around and order enough coffee for the coffee breaks.
Most participants are in B&B Hotel Essen, Helmut-Käutner-Straße 4, 45127 Essen (very close to the math department), Phone: 0201 616960. If you have not yet booked a room, you should contact the hotel as soon as possible. We have reserved a few more rooms until Friday, Feb. 8 (mention “Math Institute/Prof. Görtz”).
All talks will take place in the math building of the University of Duisburg-Essen, Thea-Leymann-Str. 9/Altendorfer Str. 11, 45127 Essen, seminar room N-U-3.04 (3rd floor, north wing).
To get to the math department from the main station, take the U-Bahn to Berliner Platz. From there, walk down Altendorfer Str. In the ground floor of the building, there is a large Conrad Electronics store, so the building is easy to find.
