摘要翻译:
我们研究了在什么情况下可以从同构类的关联函子重构堆栈。这是可能的,令人惊讶的经常:我们表明,模堆栈的许多标准例子是由它们的函子决定的。我们的方法似乎展示了新的Anabelian类型的现象,其形式是在分组中编码自同构数据的方案类别中的结构。

英文摘要:
We study the circumstances under which one can reconstruct a stack from its associated functor of isomorphism classes. This is possible surprisingly often: we show that many of the standard examples of moduli stacks are determined by their functors. Our methods seem to exhibit new anabelian-type phenomena, in the form of structures in the category of schemes that encode automorphism data in groupoids.
