Given a subobject-structured category \(\mathcal X\), we construct a new category whose objects are the pairs (X, c) where X is an \(\mathcal X\)-object and c is an idempotent, monotonic and extensive endomap of the subobject lattice of X, and whose morphisms between objects are the closed maps between the corresponding subobject lattices. We give a sufficient condition on \(\mathcal X\) for the new category to be cartesian closed.

具有幂等闭合算子和闭合态射的类的笛卡尔闭合性
给定一个子对象结构化类别\(\ mathcal X \),我们构造了一个新类别,其对象是对(X, c),其中X是\(\ mathcal X \)- object,而c是等幂,单调且X的子对象晶格的扩展内映射,其对象之间的态射是对应的子对象晶格之间的闭合映射。我们在\(\ mathcal X \)上给出足够的条件,以使新类别成为笛卡尔封闭的。
