The exam from spring 2020 is now available. We will look at the solution on April 12th.

There will be no lecture today, Tuesday 23rd of March at 10.15. If there are some question, send an email, or call me at 73591750, 48293975, or set up a zoom-meeting or a skype meeting.

The NTNU-campus, Trondheim, is closed down at least until February 17th, so we have to go back to digital teaching next week. I will try to activate the use of the same link on Zoom as the one which was used before February 1st.

I can be reached by Zoom, by skype, by email or by phone if anybody has some problem or exercises they would like to discuss with me.

Problem session 3 is moved to 16th of February.

Problem session 2 is moved to February 9th.

We are now finished with the Fundamental Theorem of Galois theory.

It seems like we can start regular teaching again. We will meet on Monday 1st of February at 14.15 in room F2.
On Tuesday the 2nd of February the lecture will be given in H1 at 10.15.

NB! First lecture will be Monday January 11th 2021 at 14:15-16:00,Room F2
This lecture will be given online and will contain a historical survey of Galois theory
with its background in solving polynomial equations by radicals.
