Webrelaunch 2020

Algebra (Winter Semester 2011/12)

  • Lecturer: PD Dr. Stefan Kühnlein
  • Classes: Lecture (0102200), Problem class (0102300)
  • Weekly hours: 4+2
  • Audience: mathematics (5.-9. semester)

We will continue the course "Einführung in Algebra und Zahlentheorie" started in summer 2011, thereby preparing more advanced topics such as algebraic number theory and algebraic geometry.

There will be a tutorial by Jonathan Zachhuber on mondays, 09:45-11:15, in 1C-01.

The results of the evaluations are to be found here: lectures,problem sessions.

Jonathan will give an additional tutorial for your questions on Monday, 5th of March, 11.30 in the room 1C-01. You may hand in your questions in advance by sending him (or your teaching assistant) an e-mail.

We will first discuss some group theoretic notions and afterwards turn to Galois theory and its most important applications. We will also discuss valuations of fields and Dedekind domains.

If there are mistakes in any sheet or solution please contact me.

Corrected sheets are returned in the tutorial or in problem class. Afterwards I will put them in the box next to room 4A-05 (Allianzgebäude). The box is labeled 'Einführung in Algebra und Zahlentheorie'.


As announced in the lectures, there will be oral examinations.


There exist lecture notes in german: algebraws2012.pdf We occsionally refer to the lecture notes einfalgzahl.pdf covering the course "Introduction to Algebra and Number Theory" from summer 2011.

Here are my slides on the construction of the regular 17-gon.
