摘要:
我们研究由(大多为小的、大多为稠密的)满子范畴$A \subset K$诱导的codensity单子$T$。这类单子表现出高度相似性,我们揭示了其与Isbell对偶、pro-有限对象及紧致空间的若干关联。我们证明这类单子极不具备可及性。最后,我们引入generic幂等单子的概念并评述其性质。
英文摘要:
We study codensity monads $T$ induced by (mostly small, mostly dense) full subcategories $A \subset K$. These monads behave quite similarly, we show some connections with the Isbell duality, pro-finite objects and compact spaces. We prove that they are quite unlikely to be accessible. Finally, we introduce the notion of generically idempotent monad and comment its properties.
