摘要翻译:
我们给出了叠加上的束集的同伦理论刻划,更一般地,给出了树状小中心C上群的预束集的同伦理论刻划。我们用它证明了束集和拟相干束集的同伦不变性和广义下降陈述。作为推论,我们得到了Hovey的广义变环定理的另一个证明。

英文摘要:
We give a homotopy theoretic characterization of sheaves on a stack and, more generally, a presheaf of groupoids on an arbitary small site C. We use this to prove homotopy invariance and generalized descent statements for categories of sheaves and quasi-coherent sheaves. As a corollary we obtain an alternate proof of a generalized change of rings theorem of Hovey.
