论文摘要
在相干类别中，子对象的posets具有非常强大的特性。我们强调了这些属性在一般类别中对良好行为的子对象类别的有效性。作为应用程序的一个例子，我们研究了可以普遍与预处理相关的各种扭转理论的问题。
In a coherent category, the posets of subobjects have very strong properties. We emphasize the validity of these properties, in general categories, for well-behaved classes of subobjects. As an example of application, we investigate the problem of the various torsion theories which can be universally associated with a pretorsion one.
