用幂locale单子表示几何态射

Representing geometric morphisms using power locale monads

Christopher Townsend

摘要:

它表明,基本拓扑之间的几何态射可以表示为相应的locale范畴之间的映射。这类算子的特征是保持序充实、与双幂局部单子交换、其右伴随保持有限余积。它们也被描述为那些保持秩序丰富和与上下权力场所单子交换的规则。

英文摘要:

It it shown that geometric morphisms between elementary toposes can be represented as adjunctions between the corresponding categories of locales. These adjunctions are characterised as those that preserve the order enrichment, commute with the double power locale monad and whose right adjoints preserve finite coproduct. They are also characterised as those adjunctions that preserve the order enrichment and commute with both the upper and the lower power locale monads.
