Referring to Ellingsrud?s book, version 3.0
1, 2.1 - 2.3, 2.5 - 2.8, 4.1 - 4.6, 5.1 - 5.3, 6.1 - 6.4, 7.1 - 7.3, 9.1 - 9.4, 10.1 - 10.3, 11.1, 11.3 - 11.4, 12, 13.1 - 13.2, 13.4, 13.6, 15.1 - 15.2
Just to clarify some details in the last message; if a student at the day of exam has any symptoms which prevents her/him to attend the exam, or is in quarantine, she/he should inform the University (/english/studies/examinations/illness-postponed/index.html). Only self-notification is required.
Even if the University of Oslo normally offers the possibility of special examination arrangements, due to significant disadvantage in an examination situation, including risk or fear of being infected by the Covid-19 disease, this will NOT be an option this fall. The University will not provide alternative locations/rooms in any cases. If any of the candidates by no means will accept an ordinary examination procedure, taking place in Silurveien, we have to rearrange the examination for the whole group.?

There has been a little back and forth about the exams this semester due to the covid-19 situation, but it now seems that the Faculty will allow ordinary school exams in small courses like MAT 4200 where infection control is easy to maintain. Students who can not take the ordinary exam due to illness, quarantine, or special circumstances will be allowed to take the exam at an another time and perhaps in a different form (oral exam).
If you are not comfortable with this solution, you should let me know as soon as possible and at latest Thursday, October 29th.

Under fanen podcaster ligger l?sninger til oppgavene til del 1. L?sningene er delt i 3 deler, der delene p? tre m?ter tar for seg hver tredje oppgave. Det burde gj?re det lettere ? veksle mellom ? se p? l?sninger og ? pr?ve p? oppgavene p? egen h?nd.
Here are some exercises from the two first chapters:

Welcome to MAT 4200 Commutative Algebra, fall 2020!
We hope to be able to have ordinary lectures during the whole semester, but in case of obstructions due to the pandemic situation, we also prepare for digital lectures.
Textbook this semester: G. Ellingsrud; Commutative Algebra, version dated August, 21. You will find a copy on the webpage (Under Syllabus).
If you have any questions, please contact me. If you want to discuss something we can either do it "live" in the Abel building, or we can schedule a digital meeting (Zoom).
