Open problems

This page lists a few open problems I'm interested in. It should be seen as a personal page I don't mind making public, because I will not take the time here to explain the full details of everything I mention. However, I have sometimes provided a few references I know about on the subject, which you can access by clicking the corresponding "bib" link. For further information, my publications may also help. If you have ideas, don't hesitate to get in touch: I'm always up for teamwork, and I'd really like to have more coauthors. Updated stuff will be in red and/or brought back on top of the list.

(I also maintain a page that summarises all open problems from ISGCI)
