**Prerequisites**-
**M3150**Algebra II &&**M1120**Discrete Mathematics

Basic courses in set theory, discrete mathematics and algebra. **Course Enrolment Limitations**- The course is also offered to the students of the fields other than those the course is directly associated with.
**fields of study / plans the course is directly associated with**- Mathematics (programme PřF, M-MA, specialization Discrete Mathematics)

**Course objectives**- The course deals with more demanding topics from lattice theory and ordered sets. The first theme will be the existence of free objects in categories of semilattices, lattices, distributive lattices, and Boolean algebras, and their complete counterparts - complete semilattice, complete lattices, frames, and complete Boolean algebras. Another topic will be algebraic and continuous ordered sets, including the introduction of Scott's topology. Using duality between coherent frames and distributive lattices through the theory of ideals, we prove Stone's duality between Boolean algebra and Stone's spaces. Finally, we touch the connection between C*-algebras and quantales.
**Learning outcomes**- At the end of this course, students should be able to: * define more demanding notions of lattice theory and ordered sets; * explain learned theoretical results; * apply learned methods to concrete exercises.

**Teaching methods**- Lectures and discussion.
**Assessment methods**- Lecture with discussions. The exam is oral with written preparation.

Successful passing of the exam presupposes presentation of the selected topic. **Language of instruction**- Czech
**Further comments (probably available only in Czech)**- Study Materials

The course can also be completed outside the examination period.

The course is taught only once. **Teacher's information**- The lessons are usually in Czech or in English as needed, and the relevant terminology is always given with English equivalents. The target skills of the study include the ability to use the English language passively and actively in their own expertise and also in potential areas of application of mathematics. Assessment in all cases may be in Czech and English, at the student's choice. The course can also be completed outside the examination period.
