The final lecture takes place Thursday. We will discuss the exam from 2017 and maybe problem 8 and 9 of the exam from 2016.
You find the solutions below.
Solutions of past exams:
Today I completeted the proof of Godel's 1st Incompleteness Theorem. Next week we will discuss the exercises in Chapther 8 (after I will talk 10 minutes about Godel's 2nd Incompleteness Theorem). The last lecture will take place on Thursday November 21.
I have completed the list of those who are qualified for the final exam.
Please check in Canvas that you are on the list if you should be on the list (everyone who has handed in the mandatory assignment should be on the list). Please inform me if something is wrong.
