MEASURE AND INTEGRATION (FALL 2016)

The main text for the course is "Real Analysis" by E. Stein & R. Shakarchi (Princeton University Press). The example sheets are available here

Sheet1, Sheet2, Sheet3Sheet4Sheet5

Sheet6Sheet7Sheet8Sheet9

There is also a set of Notes which follow very closely the book. They now contain all material that has been lectured. Please email me for typos and corrections.

Update (14/1/2017): A small section has been added at the end of the notes which is relevant for Mastery Students only.

Update (16/3/2017): Some typos in the Example Sheets (7-9) have been corrected.
