This is a list of questions that I have not managed to solve yet, or that I think should be left to others. If you have any solution, total or partial, please contact me at `goubault (at) lsv.fr`

.

I am looking for brilliant students in the field. Finding a solution to one of those problems may convince me that I should hire you!

I’ll update that list from time to time, adding new problems, removing solved problems, and so on. I am not offering any guarantee that this will change often!
