Unnatural transformations

Unnatural transformations


Given categories C,DC,D and functors F,G:CDF,G\colon C \to D, an unnatural transformation from FF to GG consists of, for each object xx of CC, a morphism from F(x)F(x) to G(x)G(x) in DD.

Thus a natural transformation is an unnatural transformation that satisfies an extra property, namely naturality.
