| Aims |
|
The study of some notions and basic results in the category theory. Using examples from other topics of algebra (studied before), it will be characterized in the terms of some universal properties of the main constructions in mathematics and the natural aspect of certain connections between them. |
| Content |
|
Necessity of axiomatization of Set Theory, elements of Godel-Bernays axiomatic theory.
Category and subcategory. Duality principle. Special morphisms in a category. Special objects in a category. Subobjects and quotient objects. Kernels and cokernels. Normal subobjects and conormal quotient objects. Exact categories. Products and coproducts. Semiadditive, additive and abelian categories. Functors. Natural transformations. |
