Expected learning outcomes
Learning the basic results in Algebraic Number Theory. Ability of computing the class groups and the group of units of a number field.
Course syllabus and organization

Unique edition

Responsible
Lesson period
Second semester
Prerequisites for admission
Basic knowledge of algebra (Algebra 1-4) and analysis (Analisi Matematica 1-4).
Assessment methods and Criteria
The exam consists of a written test and an oral examination in the same session. The written part is made of written exercises (like a computation of the ring of
integers, the class group and the group units of a number field). It is not
possible to use notes, books or calculators.
Number Theory (first part)
Course syllabus
First properties of a number field: norm, trace, discriminant and ring of integers (review of some of the arguments of the Algebra 3 course). Dedekind rings, factorization of ideals and ramification. Theorem of Minkowski. Theorem of Hermite. Theorem of Dirichlet and regulator of a number field. Dedekind ζ function. Class number formula. Other more advanced topics, time permitting.
Teaching methods
Whole class teaching of theory and excercises.
