Zusammenfassung:
|
For a
given inverse immage-preserving set-endofunctor $F$ we enrich the category of
$F$-coalgebras by partial homomorphisms. We demonstrate a factorization lemma
and an extension lemma for partial homomorphisms. Finally we completely
characterize all inverse immage-preserving
functors for which our extended category of coalgebras has a terminal object. |
