论文摘要
我们使用SPAN类别的商来介绍纹波台的语言。我们还研究了逻辑关系及其从中得出的跨度类别的商。作为一个应用程序，我们表明，当形态是逻辑函数时，布尔式饰面的类别是polesises类别的反思性子类别。
We use quotients of span categories to introduce the language of a topos. We also study the logical relations and the quotients of span categories derived from them. As an application we show that the category of Boolean toposes is a reflective subcategory of the category of toposes, when the morphisms are logical functors.
