最终余代数的逻辑构造

Logical Construction of Final Coalgebras

Luigi Santocanale

摘要:

证明了范畴$C$的每个有限多项式内函子都有最终余代数,如果$C$是局部笛卡尔闭的,有有限个不相交的余积和一个自然数对象.更一般地,我们证明了这样的内函子的余代数范畴具有所有有限极限。

英文摘要:

We prove that every finitary polynomial endofunctor of a category $C$ has a final coalgebra if $C$ is locally Cartesian closed, has finite disjoint coproducts and a natural number object. More generally, we prove that the category of coalgebras for such an endofunctor has all finite limits.
