INF9840 – Computability theory
Schedule, syllabus and examination date
This course gives an introduction to classic computability theory (also known as recursion theory). The course covers the following topics: primitive recursion, computable functions and computable indices, semi-computable and computably enumerable sets and undecidability.
We will use the computability theory we develop to prove:
- Undecidability of the halting problem
- Undecidability of the Entscheidungsprobem
- Godel's First Incompleteness Theorem
We will also discuss the negative solution of Hilbert's 10th problem.
Basic skills in theoretical computer science and in-depth skills in computability theory.
This course will include one of the three advanced topic.The choice of topic will be based on the students' interests. Some options are:
- subrecursive hierarchies
- computability of real numbers
- Turing degrees.
PhD candidates from the University of Oslo should apply for classes and register for examinations through Studentweb.
If a course has limited intake capacity, priority will be given to PhD candidates who follow an individual education plan where this particular course is included. Some national researchers’ schools may have specific rules for ranking applicants for courses with limited intake capacity.
PhD candidates who have been admitted to another higher education institution must apply for a position as a visiting student within a given deadline.
