Analytic number theory studies the distribution of the prime numbers, based on methods from mathematical analysis. Of central importance is the study of the Riemann zeta function, which embodies both the additive and the multiplicative structure of the integers. It turns out that the location of the zeros of this meromorphic function is intimately linked to the distribution of the primes. At the end of the nineteenth century, this insight led to the celebrated prime number theorem. The zeta function has been subject to intensive research ever since, but many fundamental questions remain open, of which the Riemann hypothesis undoubtedly is the most famous.
Key words for the course: Arithmetic and multiplicative functions, Abel summation and Möbius inversion, Dirichlet series and Euler products, the Riemann zeta function, the functional equation for the zeta function, the gamma function, The Mellin transformation and Perron's formula, the prime number theorem, the Riemann hypothesis, Dirichlet characters, Dirichlet's theorem on primes in arithmetic progressions.
Prerequisites: Complex Analysis corresponding to what is covered by TMA4120 Matematikk 4K.

The first lecture: January 8. It was decided during the first lecture that the lecture originally scheduled for Wednesday be shifted to Monday. There is therefore NO LECTURE on January 9.
Harold Davenport, “Multiplicative Number Theory", Third Edition, Springer Graduate Texts in Mathematics. The lectures will to a large extent be based on this book, but some supplementary material will also be considered. In particular, in the beginning of the course, we will pick some material from the first chapters of Tom M. Apostol, "Introduction to Analytic Number Theory", Springer Undergraduate Texts in Mathematics. Both books are available online from Universitetsbiblioteket.
The syllabus for the course is as defined by the lectures described in detail below. I expect you to be able to present the basic concepts and ideas discussed during the lectures. The exercises should be viewed as an integral part of the syllabus.
The final lecture took place on March 19. You are supposed to work on the topic for your oral presentation during the four remaining weeks of the semester.
You are welcome to work on the exercises in room 1329 SB2 on Friday 14:00–15:00, under my guidance, as indicated below. Solutions to the problems will be provided in due course.
As part of the oral exam, the students should give short presentations of topics assigned to them. These are topics that are not covered by the lectures. You may choose a topic yourself (to be approved by me) or choose one from the following list:
Oskar Vikhamar-Sandberg
)The aim of the presentations is to convey to your peers what the topic is about and the most important and interesting problems and results associated with it. You are not expected to study proofs of deep theorems, but you should be able to say a little more than what we can find on the Wikipedia. You may choose to give a blackboard lecture or a Beamer/Powerpoint presentation. Each presentation should last for about 15–20 minutes.
Please let me know your choice of topic before March 29. There should be only one student per topic. Once a topic is chosen, I will make a note of it in the list above. Accordingly, we follow the principle of "first-come, first-served" when assigning topics.
The oral presentations will be given on May 8. You are strongly encouraged to be present at all the presentations! Oral examinations will take place on May 9. Both events will take place in Room 656 SB2.
Before the Easter break, I will be available for consultation until April 3. I will be traveling April 4 – 11, and will again be available on April 12. After the Easter break, I will be available only May 6 – 7.
You may in principle come at "any" time during the days I am in my office, but I would recommend that you contact me in advance to make an appointment.
