Modern algebra, number theory, topology, and geometry make extensive use of the language of modules and categories. In this course, a first introduction into these abstract theories is provided.
We study modules over a ring (a common generalization of abelian groups and vector spaces), exact sequences (a powerful tool to work with generalizations of the 'isomorphism theorems'), tensor products, categories and functors. We make a start with homological algebra which combines techniques from 'modules' and 'categories'.

0.4 (40%) Midterm exam | |
|
0.6 (60%) Final exam |
There will be weekly homework, leading to a homework grade H.
Final grade:
In particular, a grade <5 cannot be compensated with homework, and handing in homework can never lead to a lower final grade.
There is one retake covering both the midterm and final exam.

Prerequisites: Algebra 1, Algebra 2, Linear Algebra, Topology.
Occasionally we will use examples coming from other mathematical subjects such as Representation Theory or Galois Theory. These are not crucial to the course.
