Terence Tao will be teaching online course Classical Fourier Analysis at UCLA from 30 March 2020. 

Course covers the following topics:

• Restriction theory and Strichartz estimates
• Decoupling estimates and applications
• Paraproducts; time frequency analysis; Carleson’s theorem

Lecture notes will be made available on this blog.

• The first class is Monday Mar 30.
• Note for non-UCLA participants: You will be permitted to attend the Zoom lectures and to post comments on the blog (one can use this post in particular for general questions about the course).

• Instructor: Terence Tao, tao@math.ucla.edu, MS 6183.  [Note for non-UCLA participants: I will not have time to respond to individual email inquiries about the class. Please use the blog for such inquiries.]
• Lecture: MWF 2-2:50pm PT, held online at https://ucla.zoom.us/j/9264073849 .  Note that access to this Zoom meeting room may be restricted outside of lecture times, or used for other purposes (such as other online seminars).  Also, while I am not recording these classes, bear in mind that I cannot prevent the video for these rooms from theoretically being recorded by third parties.
• Discussion section: N/A
• Office Hours: Th 2-3:50pm PT, online at https://ucla.zoom.us/j/9264073849 In addition, students are encouraged to use the blog comment feature, as well as start discussions in the forum. [Note for non-UCLA participants: you have read-only access to the forum.  You can use the comment thread at this blog post as a substitute.]
• Textbook: There is no required text; instead, lecture notes will made available on Terence Tao’s blog.  We will not directly follow these texts, but Demeter’s “Fourier Restriction, Decoupling, and Applications” and Muscalu-Schlag’s “Classical and multilinear harmonic analysis” (both volumes) will be relevant resources.  For Carleson’s theorem, this paper of Demeter (focusing on the slightly simpler Walsh model analogue of the theorem) can also be consulted.
• Prerequisites: A high grade in Math 247A (such as the previous quarter’s class) is required for enrollment. [Note for non-UCLA participants: Math 247A covered the following topics: A_p weights and maximal and vector maximal functions, Calderon-Zygmund convolution kernels, Sobolev embedding, the Mikhlin multiplier theorem, the square function, Littlewood-Paley theory, fractional product and chain rules, and oscillatory integrals.]

The Norwegian Academy of Science and Letters has decided to award the Abel Prize for 2020 to Hillel Furstenberg from Hebrew University of Jerusalem, Israel, and Gregory Margulis from Yale University, New Haven, CT, USA “for pioneering the use of methods from probability and dynamics in group theory, number theory and combinatorics.”

Two key figures in French mathematics, Cédric Villani, Fields medalist in 2010, and Artur Ávila, the French-Brazilian winner of the prestigious prize in 2014, engage in an informal conversation with Christoph Sorger, director of the CNRS National Institute for Mathematical Sciences and their Interactions (INSMI).

This conversation touches an aspect of a life after winning Fields medal, interactions with mass media, about Henri Poincaré, a culture of mathematics, and message to young researchers.

By the twentieth century, mathematics had advanced into rather abstract realms, transcending its origins, which had been largely driven by questions closer to the natural world. Physics on the other hand, especially after the development of quantum mechanics, went in directions that were much harder for mathematicians to appreciate. Two of our speakers this afternoon, both Karen Uhlenbeck and Tom Lam, drew attention to the fact that it is actually extremely difficult for mathematicians to understand quantum field theory. And that’s been an enduring mystery.

Since quantum field theory has been increasingly central in physics since the late 1920s, that has created, just in the logic of mathematics and physics, a gulf between them. And that was enhanced after World War II. In the quarter-century after World War II, there was an incredible flood of discoveries in fundamental physics, so that the progress of physics was largely driven by experiment in a way that might not have made the subject seem too enticing to mathematicians, especially given that the mathematical foundations were so murky. That would be kind of a summary of where the world was when I was a student, for example.

When I was a student, a physics graduate student would not be exposed—I was not, and I think others would not have been either—to any ideas at all in contemporary mathematics or really even in twentieth- century mathematics, practically. Now, clearly, things have changed a lot since then. And one of the biggest reasons that things have changed is that when the Standard Model of particle physics developed, theory, in a way, had caught up with experiments. When the Standard Model was in place, it led physicists to ask new kinds of questions that weren’t possible before, without the Standard Model. And it made what physicists could potentially do more interesting mathematically.
So, definitely, this story has changed in the period since I was a graduate student. And string theory has also been an important part of that change. I would like to remark though that although there has been a huge change since I was a student, we shouldn’t exaggerate. There is also still a big separation, an almost inescapable separation, between the goals and nature of the two subjects.

Physicists usually are not much interested in the details of mathematical proofs, which means that usually even physicists might not really understand deeply the mathematical ideas that they are working with. And, on the other hand, since the difficulty for mathematicians to understand quantum field theory has endured, it remains extremely difficult for mathematicians to understand what physicists are really trying to do.—Edward Witten, Charles Simonyi Professor in the School of Natural Sciences, in conversation with Robbert Dijkgraaf, IAS Director and Leon Levy Professor
