Course objectives

The aim of the course is to define basic mathematical concepts such as set, relations, function and order, and to motivate basic concepts of category theory.

Category theory is one of the basic disciplines of theoretical mathematics and in last decades it has become one of the basic frameworks for describing the connections between abstract mathematical concepts.

The strength of theoretical mathematics is in finding analogies between analogies and on this task no other mathematical theory can be compared with the theory of categories. The peculiarity of category theory in relation to other abstract mathematical theories is its direct applicability in the natural and social humanities and in connecting different concepts into one whole.
