Workshop and Masterclass on Homological stability

The University of Copenhagen

August 26-30, 2013

The program of the workshop/masterclass will consist of two lecture series: 

In addition there will be a few individual research talks and plenty of time for discussion. The workshop will start at 9:30 on Monday and end at 15:00 on Friday

Reading material: 

Here are some tips for how to prepare for the lectures: 

Functor homology: Draft of notes part 1 (lecture 1-4, Vespa) and part 2 (lecture 5, Djament) for the course. (Part 1 of the notes will be updated regularly in the coming days).

FI-modules: Section 2 of arXiv:1204.4533 as well as the following from the paper arXiv:1210.1854: the basic property that FI-modules over Noetherian rings are Noetherian, the complex denoted \tilde{S}_{-*} V which is defined in Section 2, and the connection between this complex and the homology of congruence subgroups in Section 3.

How to get there


See the department calendar for abstract of the afternoon talks. 

Notes for the talks are linked to the schedule (after the talks).

Venue: Centre for Symmetry and Deformation, KU. For information how to get to the Department of Mathematical Sciences click here. All talks will take plce in Aud 10. 

Registration: If you want to participate, send an email to

Accommodation: We recommend Hotel 9 Små Hjem, which is pleasant and inexpensive and offers rooms with a kitchen. The small Hotel Rye is also a good local option. Other inexpensive alternatives are CabInn that has several locations in Copenhagen: the Hotel City (close to Tivoli), Hotel Scandivania (Frederiksberg, close to the lakes), and Hotel Express (Frederiksberg) are the most convenient locations; the latter two are 2.5-3 km from the math department. Somewhat more expensive - and still recommended - options are Hotel Nora and Ibsen's Hotel

Funding: We have a limited amount of funding available. Participants can expect to get up to 2500 DKK. To apply, please send an email to with a short research description or a link to a personal webpage providing information about your research. The deadline for application is June 30, 2013.
