Semester of Instruction


Objectives and Content

Category Theory is a mathematical language and a toolbox that can be used for formalising concepts that arise in our day-to-day activity. It is highly adequate for computer science because the instruments that it provides are sophisticated and make it easier to model and to reason about situations that are complex and involve structured objects. Category Theory focuses especially on the relations between the objects of interest and on different construction principles for objects.

Learning Outcomes

After the successful accomplishment of the course INF223 the students shall

  • be familiar with basic categorical concepts, results, and constructions including category, functor, natural transformation, functor category, slice category, pullback, pushout
  • be able to explain those concepts, results, and constructions by examples from informatics
  • be acquainted with categorical reasoning and shall be able to prove basic theorems
  • have basic capabilities to use category theory to structure and to
  • formalize typical complex situations in informatics involving structured subjects under study
  • be able to acquire necessary continuative subjects from the literature

Required Previous Knowledge
