Algebra II: Commutative Algebra
- 4h Course, 10 ECTS
- Eligible as BMS Basic Course in area 2
course is the continuation of the Algebra I  course given by
Dr. Dirk Kussin  at TU Berlin in WS 19/20.
The course Algebra I  explained the basic notions of algebra: groups, rings, fields, factor structures, and provided a fairly detailed treatment of algebraic field extensions, culminating in the beautiful Galois theory.

Due to the current situation, the course will be given online. Complementary material accompanying the lecture will be provided. This will be a new experience for all of us: we have to see how well it goes! To start with, we try to keep the schedule as announced in the Vorlesungsverzeichnis.
People interested to participate in the course are
asked to send an email to Peter Bürgisser 
(pbuerg at math.tu-berlin.de) with cc to Philipp Reichenbach 
(reichenbach at tu-berlin.de), and to register
at the corresponding ISIS  course website (NEW).
Shortly before the first meeting on April 21, you will then obtain an invitation along with further instructions.
The main goal of Algebra II is to provide an introduction to commutative algebra. This is the branch of algebra that studies commutative rings, their ideals, and modules over such rings. Important examples of commutative rings are rings of algebraic integers (which includes the ring of integers) and polynomial rings over fields and their factor rings. Both algebraic geometry and algebraic number theory build on commutative algebra. In fact, commutative algebra provides the tools for local studies in algebraic geometry, much like multivariate calculus is the main tool for local studies in differential geometry.
Probably the best entry to the subject is the following short,
concise, and clearly written textbook:
Atiyah, M.F.; Macdonald, I.G.: Introduction to commutative algebra. Addison-Wesley Publishing Co, 1969 ix+128 pp.
The current plan is to follow this book quite closely. We plan to complement this with some additional material concerning algorithms (Gröbner bases).
