Workshop "Polynomial Functors and Schur Algebras"
Thursday, 07 November to Saturday, 09 November 2013
Polynomial functors and Schur algebras have their origin in Schur's seminal work, starting with his thesis from 1901. Since then, these concepts have become increasingly relevant in various parts of mathematics, most prominently in representation theory and algebraic topology. The goals of this workshop are to provide an introduction, report on recent developments and encourage dialogue among experts from different areas of mathematics who study polynomial functors and Schur algebras.
Location: Bielefeld University, all lectures will be held in room V2-210/216
Schedule: Talks start Thursday 10am and finish Saturday around 1pm.
Organisers: Andrew Hubery, Henning Krause
Support: DFG CRC 701 "Spectral Structures and Topological Methods in Mathematics", DFG SPP 1388 "Representation Theory"
If you would like to attend the workshop, or have further questions, please contact one of the organisers. We expect to receive funding to support financially participants from the networks SPP 1388 (Germany), GDRI 571 (France), and Repnet (UK). Participants arrange their own accommodation (see here for options); please contact the secretary Frau Zelmer if you need help.
