In order to be elegible for the exam for the first part, you have to produce in written form
the solutions of some exercises which will be posted here below. Then, a written exam (3/4 problems,
2 hours) + oral discussion.
For the advanced part, you have also to prepare a one-hour seminar discussing an argument
which has to be communicated to (and approved by) me in written form (LaTeX/PDF) at least
two weeks in advance.
