Workshop

Postmodern Ringel duality, bocses and contramodules

April 3 to 6, 2023
















Lecture series by Raymundo Bautista, National Autonomous University of Mexico, Unidad Morelia
Teresa Conde, University of Stuttgart
Julian Külshammer, Uppsala University
Leonid Positselski, Czech Academy of Sciences, Prague


Schedule This workshop allows researchers in the area to meet and to collaborate and it allows researchers in neighbouring areas to learn about recent developments and to meet experts. Therefore it combines a traditional workshop format with the opportunity to do research in small groups. There will be lecture series and further talks, but also plenty of time for discussions and collaboration.
Lectures will start on Monday morning, April 3, and end on Thursday, April 6. In addition, Sunday, April 2, and Friday, April 7, and subsequent days are reserved for discussions and collaboration.
The detailed schedule is here.


Abstracts Here are titles and abstracts of the talks.


Poster Here is a poster (pdf).
