拟凝聚层范畴间的张量函子

Tensor functors between categories of quasi-coherent sheaves

Martin Brandenburg, Alexandru Chirvasitu

摘要:

对于拟紧拟分离方案X和任意方案Y,我们证明了拉回构造实现了态射的离散范畴Y --> X与上连续张量函子范畴Qcoh(X)--> Qcoh(Y)之间的等价性.这是一个改进的结果卢里和可能被解释为声明,代数几何是2仿射。此外,我们证明了这个结果的类似版本的Durov的概念的广义计划在F_1。

英文摘要:

For a quasi-compact quasi-separated scheme X and an arbitrary scheme Y we show that the pullback construction implements an equivalence between the discrete category of morphisms Y --> X and the category of cocontinuous tensor functors Qcoh(X) --> Qcoh(Y). This is an improvement of a result by Lurie and may be interpreted as the statement that algebraic geometry is 2-affine. Moreover, we prove the analogous version of this result for Durov's notion of generalized schemes over F_1.
