Semester page for MAT2200 - Spring 2023

The grading for this year is now complete and submitted to the administration, and it will be available for you to see shortly.

There were 34 students who took the exam, and the distribution of grades was as follows: A 18%, B 21%, C 29%, D 3%, E 9%, F 21%.

Each of the twelve subproblems were weighted equally by 8,33 points, so that a perfect score on each problem gives 100 points. The point cutoff for each grade was as follows: A 90, B 77, C 58, D 46, E 39.

The problems and suggested solutions for the final exam are now posted: Exam and solutions. Grading will be completed by 21 June at the latest.

The slides for the revision on fields are now posted here.

The slides from yesterday's revision on rings are found here.

The corresponding slides for group theory are here.

Next week the plan is to do revision of ring theory on Tuesday and field theory on Thursday, as well as for me to give example solutions of selected problems from previous years' exams.

On Friday 26 May, 12:15-14:00, in N.H.Abels hus, UE32 there will be a final question session, where you can bring questions and confusions and I will try to provide answers and clarity.

Sondre Andresen has produced a summary (in Norwegian) of the parts of Fraleigh that we cover, and has very kindly agreed to share it, see here.

Previous years' exam problems are found here and their solutions are found here.

A suggested solution to the mandatory assignments is posted here.

The following problems from previous years use Sylow theory, which we have not covered, so these problems can be ignored if you use these old exams for revision/exam practice.

2022: 1a
2020: 3
2018: 2a
2017: 2b
2014: 3c
2013: 3
2012: 1b, 1c, 1d
2011: 2b, 2c
2010: 2
2009: 1b, 1c
2006: 1c, 4
2004: 1

The mandatory assignment is now available here, submission deadline 30 March 14:30. Good luck!

I've put together a very compressed summary of what we've learned about groups in a set of slides here.

This week we finished the group theory part of the course, and will start on rings and fields (Section 18) on Tuesday. Note that sections 36 & 37 covering some more advanced group theory material were part of the original plan for what we would cover, but I have decided to remove these from the curriculum.

-J?rgen

The mandatory assignment will be posted 16 March or a few days before that, with submission deadline 30 March.

I'll post the suggested exercises for each Wednesday exercise session in the "Resources/curriculum" field in the course schedule.

Abstract algebra does, not surprisingly, involve many abstract definitions and ideas, and one of the strengths of Fraleigh's book is that it has lots of exercises to help you get used to these. If you have time, it's probably useful to do more exercises than the ones I suggest.

Student representatives (tillitsvalgte) for this course are Amund Alsvik (amundsal@student.matnat.uio.no) and Zejing Wang (zejingw@math.uio.no).

Hi all,

And welcome to MAT2200 - Groups, Rings and Fields! I have lectures on Tuesdays and Thursdays, Gaute Schwartz will host problem sessions on Wednesdays.

The textbook for the course is Fraleigh's "A First Course In Abstract Algebra", 7th edition. The tentative curriculum is sections

2-6, 8-11, 13-23, 26, 27, 29-31, 33, 36-37, 48-51, 53, 54, 56. (Updated 5/3/23 to remove 36-37).

The dashes above denote all sections in between, i.e. 2-6 means sections 2, 3, 4, 5, and 6.

Before we start lectures next week, it may be useful to have a look at Section 0, which summarises some material on how to work with and talk about sets.
