## Summary

**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, Sheet3, Sheet4, Sheet5,

Sheet6, Sheet7, Sheet8, Sheet9

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**.

The first assessed coursework is due **November 11th**. It consists of Question 1 from Sheet 1, Questions 4+5 from Sheet 2 and Questions 3+4 from Sheet 3. [Returned]

The second assessed coursework is due **December 5th**. It consists of Questions 1+4 from Sheet 5, Questions 1+3 from Sheet 6 and Question 5 from Sheet 7. [Returned]

Revision Sheet (updated 21/3/2014)

The Mastery Question will be a question combining different techniques that you have seen. It's a good idea to review the section(s) on the wave equation.
