I am a distance education student at a Parisian university, and I am currently preparing for the exam in a research-level mathematics course.
While on-campus students have attended the lectures and presentations of sample problem solutions, distance education students only get incomplete lecture notes in pdf format, sample problems without solutions, and a list of recommended textbooks.
I think I was quite successful studying about 85% of the course this way, but the last one or two lectures and sample problem solutions cover some very advanced material, which is not adequately addressed by the recommended textbooks. I also could not find this material is a sufficiently concentrated form in research articles, and I estimate that it may take thorough reading and understanding of no less than 50 articles and maybe 3 months to properly figure this out by myself.
One of the professors recommended to me that I get a copy of the lecture notes and sample problem solutions from a student that attended the course in person, but when I requested a few email addresses from the secretary, she said she is not authorized to divulge that information. I asked the other professor of this course, but got no reply. I can't go to a course lecture to locate such students, because the last lecture was some time ago.
I would like some advice on what else to try to obtain the lecture notes.
