Planned learning activities and teaching methods

Regular lectures focused on basic principles and methods of the theory of ordered sets and lattices including examples..

Assesment methods and criteria linked to learning outcomes

The students will be assessed by means of a written and oral exam at the end of the semester.

Language of instruction

Czech, English

Work placements

Not applicable.


The goal of the subject is to get students acquainted with the theory of ordered sets with a stress to the lattice theory.

Specification of controlled education, way of implementation and compensation for absences

The presence at lectures is not compulsory, it will therefore not be checked.
