On May 26 you were misinformed. The proof of Schr?der-Bernstein is not available from the home-page.
I will give the proof during one of the remaining lectures, if there is still an interest for it.
The oral exams in MAT4640/9640 will take place on Tuesday June 9.
If there are good reasons, e.g. collision with other exams, why this day is impossible, you may apply to studinfo@math.uio.no to have the exam the day after.
Details will follow later.
The solutions to the mandatory assignment is now available from the semesterpage of MAT4640
