Content of the course

The content of this course can roughly be divided into three parts.
1. Basic properties of integral rings of number fields, decomposition of primes in extensions, and Minkowski’s bound of class numbers.
2. Dedekind zeta functions, Dirichlet L-series, distribution of ideals and the residue formula.
3. Non-archimedean fields, adeles and Tate’s thesis.

The oral exams will take place from Monday, 05.02.2018, till Wednesday, 07.02.2018. The students are asked to sign up in a time schedule during the lecture course to arrange a date. Please contact the lecturer or the assistant if any of the above dates cannot be attended. The second date for the oral exams will be on Thursday, 22.3.2018.

Exercise sheets

Exercise session

There are two weekly exercise sessions accompanying the lecture. It is necessary to attend one exercise session and hand in solutions to the exercises in order to participate in the final exam. Please hand in your solutions mondays during the lecture. The regular exercise sessions start in week two. Registration for the exercise sessions takes place during the first lectures or exercise sessions. Please note that this does not replace the registration for the course module in BASIS (which includes a different registration for the exercise session) during the registration period in december.
