What this course is about? It is about 3 topics:
How do we run this course? We will have
How is this course graded? The grade will consist of participation in discussions (50%) and final (exam or essay and presentation, TBD) (50%).
It is hard to quantify participation, and I don't want to assign grade based on how many sentence you say. If one has to set a criterion, let's say, each week, you should
To measure performance, we will have a final essay and a 5-10 minutes presentation. You can choose a topic of your interests, read and write up an introduction survey, and record a video presentation. It is a bit vague for now, we can discuss how to make it work. (If this is too hard to figure out, we will just have a usual final exam)
Here is what the letter grade should mean
So, say again, where should I submit homework?
The homework will be posted at the end of each week on this website, the homework will contain questions that you have encountered in class discussion, and some more exercises from Tao.
You will submit the homework three times:
Although the homework is graded based on completion, I do hope you give each problem a serious thought. If you see a problem being too easy, you can just sketch the main steps; if you see a problem too hard, you can describe your failed attempt (or even better, ask for suggestions first on discord).
You should be able to download the first textbooks using the above links, once you login to your UC Berkeley account. The third one is advanced undergraduate level and first year graduate level book.
We will first cover Lebesgue measure and Lebesgue integral. This is covered Chapter 6 of Pugh, Chapter 7 and 8 in Tao. We will spend about about half the course doing this. Then, we consider multivariable calculus, with the goal of understanding the Stokes theorem, this is Chapter 5 of Pugh and Chapter 6 in Tao. Finally, we consider Fourier series, Chapter 5 in Tao.

For the sake of grading, we will still have an in class final. It will be an open book exam. Exam will be on May 12 (Thursday, 3-6pm, Evans 3). It will consist of 5 problems, where you will decide if a statement is true or false; if true give a proof, if false, give a counter-example.
In addition to the final, if you are interested in writing an essay (post on your homepage), or give a 15-min presentation (in the class day of class), here are some topics and you are free to choose your own.
