Course content

Axioms of Set Theory, Set Theory as a Foundations of Mathematics, Ordinal Numbers, Cardinal Numbers, Axiom of Choice, Axiom of Foundation. Cardinal and ordinal arithmetic. Basics of some additional topics such as large cardinals, constructible universe and the consistency of Continuum Hypothesis, absoluteness, non-wellfounded sets and the Anti-Foundation Axiom.

Study materials

Literature

  • K. Hrbacek and T. Jech, Introduction to Set Theory, Third Edition, Revised and Expanded, CRC Press, 1999.

Objectives

  • The student is able to derive the existence of some simple operations on sets from the axioms of set theory.
  • The student is able to show properties of ordinals using the method of transfinite induction.
  • The student is able to make computations with ordinal and cardinal numbers using (infinite) sums, multiplication, and exponentiation.
  • The student is able to conduct proofs about ordinal and cardinal numbers using the equivalent statements of the Axiom of Choice, such as Zorn's lemma, Koenig's lemma, and Zermelo's theorem.
  • The student is able to solve basic problems of cardinal arithmetic involving singular and regular cardinals.
  • The student is able to work with the cumulative hierarchy of sets using the Axiom of Foundation.

Attendance

Programme's requirements concerning attendance (OER-B):

  • Each student is expected to actively participate in the course for which he/she is registered.
  • If a student can not be present due to personal circumstances with a compulsory part of the programme, he / she must report this as quickly as possible in writing to the relevant lecturer and study advisor.
  • It is not allowed to miss obligatory parts of the programme's component if there is no case of circumstances beyond one's control.
  • In case of participating qualitatively or quantitatively insufficiently, the examiner can expel a student from further participation in the programme's component or a part of that component. Conditions for sufficient participation are stated in advance in the course manual and on Canvas.
  • In the first and second year, a student should be present in at least 80% of the seminars and tutor groups. Moreover, participation to midterm tests and obligatory homework is required. If the student does not comply with these obligations, the student is expelled from the resit of this course. In case of personal circumstances, as described in OER-A Article A-6.4, an other arrangement will be proposed in consultation with the study advisor.
