Next quarter, starting March 30, I will be teaching “Math 247B: Classical Fourier Analysis” here at UCLA. (The course should more accurately be named “Modern real-variable harmonic analysis”, but we have not gotten around to implementing such a name change.) This class (a continuation of Math 247A from previous quarter, taught by my colleague, Monica Visan) will cover the following topics:
- Restriction theory and Strichartz estimates
- Decoupling estimates and applications
- Paraproducts; time frequency analysis; Carleson’s theorem
As usual, lecture notes will be made available on this blog.
Unlike previous courses, this one will be given online as part of UCLA’s social distancing efforts. In particular, the course will be open to anyone with an internet connection (no UCLA affiliation is required), though non-UCLA participants will not have full access to all aspects of the course, and there is the possibility that some restrictions on participation may be imposed if there are significant disruptions to class activity. For more information, see the course description. UPDATE: due to time limitations, I will not be able to respond to personal email inquiries about this class from non-UCLA participants in the course. Please use the comment thread to this blog post for such inquiries. I will also update the course description throughout the course to reflect the latest information about the course, both for UCLA students enrolled in the course and for non-UCLA participants.

Should participants register for the class, or its open university style?
Given the current announcement from UCLA that teaching is transferring to online through the winter quarter, will it be possible to access other math classes also online? I don’t see why not. Hardly any other university can offer such quality mathematics content as UCLA, and this unfortunate pandemic could be the beginning of a new era of mathematics education.

At present, UCLA does not have plans to permanently transition to an online education model; for the spring quarter all classes will be given online, but it is up to each instructor whether to open their course beyond their enrolled UCLA students. In particular there is currently no way for participants not affiliated with UCLA to formally enroll in the course, and some course components (e.g., homework grading) will be restricted to UCLA students enrolled in the course. By the end of the spring quarter there may be more clarity (both with regards to the efficacy of online teaching, and on the state of the coronavirus pandemic) as to how UCLA is to proceed going forward, but at this point there is far too much uncertainty to make any predictions.

Mr. Tao,
Thank you for sharing this open
It helps in these days to exercise the mind.
Best,

a quick library search turns up this expository article about the Waring problem.

There are also some nice – rather technical – articles by Jean Bourgain.

How do we pass between discrete statements over
to statements over 
? Any time we used symbols like “
” or 
these were certainly limits of some other process.

Dear Prof. Tao,
I haven’t studied too much about the topics in the prerequisite (i.e. M247A); I did some graduate real analysis before, and we finished Chapter 1-7 in Folland and a bit of distribution theory. I am afraid that they are not enough. Could you help suggest some notes/book/reading for me to get more preparation for M247B? I searched online and found that you also wrote some notes for M247A (https://www.math.ucla.edu/~tao/247a.1.06f/), is it enough for your M247B?

FYI this was the class page for last quarter’s 247A taught by Professor Visan.

I guess one can say that Monica’s “The lectures are most strongly influenced by the following” list of references in Zane’s link covers almost ALL primary texts in “introductory” harmonic analysis. (I mean, of course, the lecture would/should be strongly influenced by those books. What could else books be?) One may feel lost…

That course covered a slightly different set of topics than last quarter’s 247A (that set is now listed in the course description), but either course should be sufficient preparation for 247B (in particular, familiarity with interpolation, Fourier analysis, and estimation of oscillatory integrals (e.g., by the method of stationary phase) will be helpful.)

This 247B seems to be quite different from the one you offered before: https://www.math.ucla.edu/~tao/247b.1.07w/

Will you put the video online after class? Like youtube

I have decided not to do this; it may negatively impact class participation, and there are also some non-trivial issues regarding consent and privacy on the part of the students. It is possible these issues are solvable, but the transition to remote teaching is going to be chaotic enough as it is, so I do not want to make things even more disruptive this quarter. However this may be a possibility for future courses for which there is more time available to prepare for such issues.

Do you expect that the participants may exceed the capacity of Zoom?
17 March, 2020 at 2:44 pm
Terence Tao
I believe the capacity of our Zoom meeting rooms is 300. I do not anticipate exceeding this limit, but if this becomes the case I will limit attendance to UCLA affiliated participants once one gets close to this limit. (It should be pointed out that this course is a continuation of a previous graduate course at UCLA and may not necessarily be suitable for external participants that do not have the appropriate prerequisites.)

Due to your popularity (see also https://zhuanlan.zhihu.com/p/113528952), I would not be surprised if the number of participants significantly exceeds the limit, even there may be a lot who don’t know much real analysis. On the other hand, serious students who do want to learn would benefit tremendously from being able to sit in the Zoom room or have access to some recordings without compromising the privacy of UCLA students.

In my ignorance of what all these specifically are about, my reaction is that these topics sound a great deal more like a workshop for researchers than a course for graduate students.

Dear Prof. Tao,
May I ask how can I attend the Zoom lectures?
Is there any kind of registration?
Many thanks,

Dear Prof Tao,
I think that as the host, you can mute audio(and video) of every participant except your UCLA students. Thank you very much.

how can we find the replay ? as timezoon difference. we can not attend the online class . please see where can we find the record session .thanks a lot.

For reasons of privacy, UCLA policy forbids video recordings to be available except to the students enrolled in the class.

Could you post your notes in .pdf format on line? They don’t need to be the final version. It is easier for students to download and take notes.

If you print a blog page to PDF you will get a readable PDF file (with the header, sidebar, etc. stripped)

It is also easy to export the file into notes using an iPad. So convenient to go paperless!

Would it violate the UCLA policy if you upload your notebook (which contains lots of useful pictures you drew in class) somewhere on your webpage?
