Apomorphism

An apomorphism (from ἀπό — Greek for "apart") is the categorical dual of a paramorphism and an extension of the concept of anamorphism (coinduction). Whereas a paramorphism models primitive recursion over an inductive data type, an apomorphism models primitive corecursion over a coinductive data type.

Origins

The term "apomorphism" was introduced in Functional Programming with Apomorphisms (Corecursion).^[1]
