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   and on topology.  
  Partially ordered sets, Axiom of choice and its equivalents, well-ordered sets, ordinal and cardinal rithmetic. Semilattices, lattices, complete lattices and lattice homomorphisms. Meet structures and closure operators, ieals and filters, Galois correspondence and Dedekind-MacNeille completion. 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 competencies:
  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 competencies:
  The graduates will be able to use modrn and efficient mathematical methods in their scientific work.
