funktorid
Funktorid is the Estonian (and related) term for functors in category theory, a mathematical concept used to describe structure-preserving mappings between categories. In a broader sense, funktori provide a formal way to translate objects and their relationships from one mathematical setting to another while respecting the underlying composition rules.
Formally, a funktor F from a category C to a category D consists of two components: a
There are covariant and contravariant funktori. Covariant funktori preserve the direction of arrows, while contravariant funktori
In practice, funktori form the morphisms between categories, and their study interacts with natural transformations, adjunctions,
