论文摘要
我在一个名为“ Atlases”的格罗氏菌站点中介绍了一类图表，该图表可用于研究超散发体，并表明Hypersheaves使用索引的“神经”结构将Atlases带到限制，从而产生了从地图酶中产生HyperCovers的构建。地图酶的灵活性同时比超植物更明确，更普遍。
I introduce a class of diagrams in a Grothendieck site called "atlases" which can be used to study hyperdescent, and show that hypersheaves take atlases to limits using an indexed `nerve' construction that produces hypercovers from atlases. Atlases have the flexibility to be at the same time more explicit and more universal than hypercovers.
