September 30: I just posted the first chapter of my notes.

October 6: The notes have been renewed.

Read my notes up to proposition 1.26 (included). Try to understand whatever is missing, e.g. things that I consider obvious. Also read carefully whatever I omitted on the blackboard, e.g. various technical details.

Try to solve the following exercises, where those with a star perhaps are more important than the others: 

From section 1.1: 2, 3, 4, 5, 6, 7, 9, 10, 13, 14, 15, 16, 18, 20, 21, 22.

From section 1.2: 3, 4, 7, 8, 10*, 11*, 15, 18(ii), 19(i). 

October 21: The notes have been renewed. I have made some changes in propositions 1.34 and 1.36.

You do not have to read section 1.5 about Borel measures on topological spaces. I have entered chapter 2 up until the sum and product of measurable functions.

Try the following exercises:

From section 1.3: 2, 3, 5*, 6, 7*, 8*, 9.

From section 1.4: 1*, 2*, 3*, 4*, 5*, 8*, 9*, 10, 11, 13, 14*, 15, 16, 17, 18.

From section 3.1: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12. 

November 11: The notes have been renewed (after some changes).

We have finished section 3.1. We did the limit theorems and the approximation by simple functions fairly thoroughly. We also did integrals over subsets and point-mass distributions somewhat superficially. Finally, we covered section 3.2 about the Lebesgue integral.

Try the following exercises:

From section 3.1: 13*, 14*, 15*, 16, 17*, 18*, 19*, 20*, 21*, 22, 23*, 24*, 25*, 26*, 27, 28, 29*, 30*, 31*.

From section 5.4: 2*.

From section 5.5: 1, 3*, 4, 6*.

We have also finished chapter 6 (not the last subsection about differentiation of Borel measures on R^n). We also did section 3.4 from chapter 3. Try the following exercises:

From section 6.2: 3.

From section 6.3: 1.

From section 6.5: 1*, 3, 6, 7.

From section 6.6: 1*, 3*.

January 8: The promised extra classes will be next week as follows: Wednesday 11-1, Thursday 2-4, Friday 11-1, all at B208. I will cover L^p spaces and their mutual duality. I would like to also cover the space of continuous functions and its dual, but I am afraid the time is not enough (the week after the next I will be away). 

January 15: Here is the promised set of exercises. They serve as a guide for the final exam.

Harmonic Analysis (undergraduate), Spring 2024-25.

Notes. They are renewed regularly.

Content: The first part of the course (two or two and a half weeks) is a quick review of the Lebesgue integral for functions defined on subsets of R. The second and main part of the course is the presentation of Fourier series for functions which are integrable or square-integrable on the interval [0,1) and of the Fourier transform for functions which are integrable or square-integrable on R. Fourier series and the Fourier transform are very important for many subjects of mathematics and the sciences and I hope that we shall find time to see a few applications.

Lectures: 3-5 Tuesday and Thursday, E204. Exercises session: 1-3 Friday, A212.

Office hours: 12-1 Tuesday and Thursday, in my office (Γ211).

Background: The courses Analysis I and II and, hopefully, a course in Real Analysis.

Bibliography: A good book is "Fourier series and integrals" of Dym and McKean. The parts of the book which are more relevant to our course are 1.1-1.5 from the first chapter and 2.1-2.6 from the second chapter.

February 23: The notes have been renewed.

March 9: The notes have been renewed.

I hope the following will help you when you read the notes. 

(i) Remember the basic properties of integrals as they are stated in sections 1.1 up to 1.4. You don't have to read the proofs. 

(ii) Read carefully section 1.5 which is about the actual calculations of integrals. 

(iii) Read sections 1.6 and 1.7 about the properties of the spaces L^1(A) and L^2(A). You don't have to read the proofs of Theorems 1.4 and 1.5. Also, we shall see later in class the part of section 1.7 which is after Proposition 1.40. Don't read it now.

(iv) In section 1.8 you don't have to read the proofs of Propositions 1.43, 1.44 and 1.45. Read all other proofs and also the alternative proof of Proposition 1.45 which uses the theorem of Fubini. 

(v) Read everything in section 1.9. 

(vi) Starting with chapter 2, read everything!

A set of exercises is coming soon!!

And here is the first set of exercises!!!

March 12: Today's lecture as well as last Thursday's lecture were lost (due to the very well known reasons). I am going to do two extra lectures: 11-1 Wednesday March 19 and 11-1 Wednesday March 26.

Moreover, I am going to add an extra session for exercises: 11-1 every Friday, starting next week.

March 19: The two extra lectures (on the two Wednesdays) will be done in A203. 

And the extra session for exercises: 1-3 every Friday in A212.

March 23: The notes have been renewed and there is a second set of exercises. You may try now the exercises 1, 2, 3, 4, 12. 

March 27: Tomorrow's exercise session will be done as announced.

April 4: The notes have been renewed. There are two small subsections, 2.1.6 and 2.2.2, under the title "a few extra things": you don't have to read them. 

April 19: The notes have been renewed. I have also rewritten the first two sets of exercises: I made some minor changes but, more important, I have included hints for most of the exercises. I hope that this helps.

A third set of exercises will follow soon: during these holy days I don't want to interrupt your dedication to praying :)

April 20: Praying is over, so here is the third set of exercises to think about over the Easter table!

May 9: Look at the new notes. (I have not done Propositions 3.14 and 3.15 yet.)

During the Tuesday lecture I was prosecuted by some of my students (of a specific gender). The accusation was: I have said a few times, during lecture time, that boys are smarter than girls. I think that I persuaded the accusers (and myself) that every time I say that boys are smarter than girls I am joking. Fortunately and for the time being I am out of jail. I look forward to see my student evaluations after the end of the semester.

May 10: Here is the fourth set of exercises.

May 25: The fifth and last set of exercises.

There will be an exercise session next week: 3-5 Tuesday, A212. (Perhaps one more.)

May 29: The last exercise session: tomorrow 1-3, A212.

Οι ασκήσεις 1.3.21, 1.3.22, 1.3.23, 1.3.24 (ειδικά αυτή) ασχολούνται με σύνολα τύπου Cantor και έχουν ενδιαφέρον. Τέλος οι ασκήσεις 1.3.4, 1.3.5, 1.3.9, 1.3.16, 1.3.17, 1.3.18, 1.3.19, 1.3.20 είναι λίγο πιο εξεζητημένες και δεν χρειάζεται να ασχοληθείτε με αυτές άμεσα.

30 Νοεμβρίου: Εδώ είναι η μέχρι τώρα ύλη. Έχουν γίνει αρκετές αλλαγές στην παρουσίαση των προηγουμένων, αλλά δεν αλλάζει η ουσία. Π.χ. το θεώρημα μονότονης σύγκλισης έχει μεταφερθεί σε μια νέα ενότητα, την οποία θα ξεκινήσουμε την ερχόμενη εβδομάδα, με τίτλο "οριακά θεωρήματα". Στην ενότητα 3.4 διαβάστε τους ορισμούς και τις διατυπώσεις των προτάσεων, χωρίς να δώσετε έμφαση στις αποδείξεις τους. Να κατανοήσετε καλά την ενότητα 3.5.

Κοιτάξτε και τις ασκήσεις 3.6.1 -  3.6.9 και 3.7.1 - 3.7.9. Λίγο πιο μετά θα αναρτήσω και την ύλη πάνω στον χώρο L^1(A) των ολοκληρώσιμων συναρτήσεων σε μετρήσιμο σύνολο A η οποία, όμως, θα είναι εκτός του τελικού διαγωνίσματος.

21 Δεκεμβρίου: Εδώ είναι η πλήρης ύλη. Επαναλαμβάνω ότι ο χώρος L^1(A) δεν περιλαμβάνεται στην εξεταστέα ύλη. Θα συμβούλευα πάντως όποιον ενδιαφέρεται σοβαρά για το μάθημα (και ειδικά όποιον ενδιαφέρεται να πάρει το μάθημα της Αρμονικής Ανάλυσης το επόμενο εξάμηνο) να διαβάσει και αυτό το μέρος της ύλης του μαθήματος.

11 Ιανουαρίου: Την ερχόμενη εβδομάδα θα είμαι στο γραφείο μου για απορίες: Δευτέρα 11:30-13:00, Τρίτη 11:00-13:00, Τετάρτη 11:00-13:00, Πέμπτη 10:00-11:30.

Advanced Harmonic Analysis (advanced graduate), Spring 2023-24.

Notes. They are renewed regularly.

Content: the Fourier transform in the spaces L^1, L^2, L^p (1<p<2), in the space of complex measures, and in the space of tempered distributions. Depending on the time left, I plan to touch some of the following extra subjects: Bochner's theorem for positive definite distributions, the Paley-Wiener theorem for distributions of compact support, the uncertainty principle, Sobolev spaces, singular integrals (e.g. the Hilbert transform and the relation to Complex Analysis), the space of functions of bounded mean oscillation, etc.

Some very good books are: "Introduction to Fourier Analysis on Euclidean Spaces" by Stein and Weiss, "Lectures on Harmonic Analysis" by Wolff, "Functional Analysis" by Yosida, "Methods of Modern Mathematical Physics" by Reed and Simon, "Fourier Analysis" by Duoandikoetxea, "Harmonic Analysis" by Helson. There are many many more!! 

April 16: the notes have been renewed.

April 18: the notes have been renewed.

April 21: here is the first set of exercises. Most of them contain important results of harmonic analysis and most of them are covered as part of the theory in many very good classical books. You will gain a lot if you try them (as exercises) following the steps I propose instead of passively reading them in a book.

April 26: the notes have been renewed. They do not contain anything about the support of a tempered distribution, but I am going to include it soon.

May 2: the notes have been renewed.

May 3: the notes have been renewed.

May 14: the notes have been renewed.

May 21: the notes have been renewed.

May 25: the notes have been renewed. In the last chapter, there is an extra proof of Proposition 9.1 and two extra Propositions, 9.2 and 9.3. The course is over, but I shall keep renewing my notes from time to time. I want to include more things about Bochner's theorem, about the Paley-Wiener theorem and about distributions of compact support. I also want to include the main facts about the Hilbert transform and about more general singular integral transforms.
