An identity natural transformation is a specific kind of natural transformation that serves as a 'do nothing' morphism between two functors. Essentially, it maps each object in the category to itself and each morphism to itself, reflecting the structure of the categories involved. This transformation highlights the concept of natural transformations as a generalization of homomorphisms, emphasizing how they preserve the relationships between objects and morphisms in a functorial way.
congrats on reading the definition of identity natural transformation. now let's actually learn it.
