[edit] Metamorphism
So, as the article is currently written the definition of a hylomorphism is self-dual... it doesn't make sense to say that a "metamorphism" is the dual concept. The definition given for a metamorphism IS NOT dual to the definition given for a hylomorphism; think about it.--128.208.1.234 (talk) 18:12, 15 July 2008 (UTC)
- Can you clarify, or improve the article yourself? It seems okay to me: Dual (category theory) claims that the dual can be formed by switching domains and codomains and reversing compositions. Do this with a hylomorphism, and you get a metamorphism. No? Angus Lepper(T, C, D) 21:18, 15 July 2008 (UTC)
