Tuesday and Thursdays, 11-12:30 in Room 4-153.
Note that the text, , is Rudin's ``Principles of Mathematical Analysis''. The problems are from the 3rd edition.
There are two sections of 18.100B, plus a section of 18.100A. This web page is only for my section. The lecturer for the other section of 18.100B is Professor S. Helgason.
The timetable here should not be completely relied upon! As set out below it will mean that we move at a quite brisk pace. Probably I will have to modify it a bit as I go along. The dates of the tests and on which homework is due will not change but it is possible that the material they cover will change a little.
