导出复体analytic geometry II:平方零扩张

Derived complex analytic geometry II: square-zero extensions

Mauro Porta

摘要:

我们继续探索衍生\canal几何开始在[DAG-IX]和http://arxiv.org/abs/1506.09042。我们把导出复解析空间$X$上的$\mathcal O_X$ -模范畴描述为$\mathcal O_X$上解析代数范畴的稳定化.最后,我们应用这种描述引入解析平方零扩张的概念,并证明了它们的一个基本结构定理。

英文摘要:

We continue the explorations of derived \canal geometry started in [DAG-IX] and in http://arxiv.org/abs/1506.09042. We describe the category of $\mathcal O_X$-modules over a derived complex analytic space $X$ as the stabilization of a suitable category of analytic algebras over $\mathcal O_X$. Finally, we apply this description to introduce the notion of analytic square-zero extension and prove a fundamental structure theorem for them.
