Objectives and competences

Student gets familiar with basic concepts point-set topology, such as connectedness, compactness, separation properties, topology on products and function spaces.

Intended learning outcomes

Knowledge and understanding: Understanding of notions such as topology, continuous map, connectedness and compactnes. Knowledge of basic concepts of the above notions and connection with other areas of mathematics.
Application: Point-set topology is one of the basic mathematical courses. Student gets familiar with basic definitions and techniques that are fondations for several other mathematical courses.
Reflection: Understanding of the theory from the applications.
Transferable skills: The ability to formualate a problem in suitable language, find a solution of the problems and analyse the method on real examples.
