N domain functors(of little practical use);
will be called here functors.
In a pre-abelian category, exact functors can be described in particularly simple terms.
Exact functors are most useful in the study of abelian categories,
a completion is any of several related functors on rings and modules that result in complete topological rings and modules.
In mathematics, certain functors may be derived to obtain other functors closely related to the original ones.
Moreover, a natural transformation between two such functors induces a homotopy between the induced maps.
As a result, this defines a category of categories and functors- the objects are categories,
they could introduce functors, and they introduced functors so that they could introduce natural equivalences.
given categories form a category, where the objects are the functors and the morphisms are natural transformations between the functors. .
The functor is in the two categories.
Identified by a functor from sets to elements.
Every faithful functor from a balanced category is conservative.
Then the fact is that the functor is an equivalence.
Every representable functor C→ Set preserves limits
This should not be confused with the concept of functor in category theory.
A functor is simply exact if it's both left exact and right exact.
For example, the tensor algebra construction on a vector space as left adjoint to the functor on associative algebras that ignores the algebra structure.
Morphisms in this category are natural transformations between functors.
Note that Hk is a contravariant functor while Hn- k is covariant.
