关于环范畴的对立面

On the opposite of the category of rings

Richard Vale

摘要:

本文定义了一个从环范畴到戴环空间范畴的忠实反变函子NCSpec,并证明了如果R是交换环,则NCSpec(R)在适当的意义下可以看作是Spec(R)的一个完备化.然后,我们解释如何空间NCSpec(R)可能是胶合,并研究拟相干层。作为一个例子,我们计算拟相干层的范畴由斜多项式环R通过类似的Proj结构。

英文摘要:

We define a faithful contravariant functor NCSpec from the category of rings to the category of ringed spaces, and show that if R is a commutative ring then NCSpec(R) may be viewed as a completion of Spec(R) in an appropriate sense. We then explain how the spaces NCSpec(R) may be glued, and study quasicoherent sheaves on them. As an example, we compute the category of quasicoherent sheaves on a space constructed from a skew-polynomial ring R by an analogue of the Proj construction.
