The topic of the course is commutative algebra, that is the study of commutative rings and modules over them. This is one of the foundations of modern algebraic geometry and therefore, indirectly, also for algebraic number theory. We will take the connection with algebraic geometry into account right from the start, so that the course provides a natural path into this exciting field, which is one of the most active ones in today’s mathematics.

**Lectures:** Mon, 10-12; Wed, 14-16; Place: S-U-3.01; First lecture: April, 9.

**Exercise group:** Mon, 12-14, Place: O-3.46, First meeting: April, 16.
