Prerequisites:  

 Learning objectives: 

  The aim of the subject is to acquaint students with modern mathematical methods used in informatics. In particular, methods based on the theory of ordered sets and lattices, algebra and topology will be discussed.  Description: 

  Naive and axiomatic (ZermeloFraenkel) set theories, finite and countable sets, cardinal arithmetic, continuum hypothesis and axiom of choice. Partially and wellordered sets and ordinals. Varieties of universal algebras, Birkhoff theorem. Lattices and lattice homomorphisms. Adjunctions, fixedpoint theorems and their applications. Partially ordered sets with suprema of directed sets, (DCPO), Scott domains. Closure spaces and topological spaces, applications in informatics (Scott, Lawson and Khalimsky topologies).  Knowledge and skills required for the course: 

  Basic knowledge of set theory, mathematical logic and general algebra.  Subject specific learning outcomes and competences: 

  Students will learn about modern mathematical methods used in informatics and will be able to use the methods in their scientific specializations.  Generic learning outcomes and competences: 

  The graduates will be able to use modrn and efficient mathematical methods in their scientific work.  Syllabus of lectures:
