Basics of Category Theory

FSI-9TKDAcad. year: 2023/2024

The aim of the subject is to make students acquainted with basic concepts and results of category theory with respect to their applications in various fields, particularly in computer science. They will be able to use the knowledge acquainted in their professional specializations.

Language of instruction


Number of ECTS credits


Mode of study

Not applicable.

Entry knowledge

The knowledge is expected of the subjects General Algebra and Methods of discrete mathematics taught within the Bachelor's level and Graph theory and Mathematical structures taught within the Master's level of the study programme mathematical Engineering.

Rules for evaluation and completion of the course

Students are to pass an exam consisting of the written and oral parts. During the exam, their knowledge of the concepts introduced and of the basic propertief of these concepts will be assessed. Also their ability to use theoretic results for solving concrete problems will be evaluated.
Since the subject is taught in the form of a lecture, which is not compulsory for student, the attendance will not be checked.


The goal of the subject is to get students acquainted with basics of the category theory and some of its applications in computer science.
Students will get basic knowledge of the category theory and will learn using them for solving some problems of computer science like creating logic circuits and flow charts.
