论文摘要
我们解释了为什么在完整的,分离的拓扑矢量空间中,对具有线性拓扑的完整,分离的拓扑矢量空间的天真定义会失败。特别是,与ARXIV相反:0711.2527,这种拓扑矢量空间的类别不是准阿贝尔语。我们提出了对确切类别结构的校正定义,该定义正常。然后,我们解释说,校正后的定义仍然存在缺点,因为它在其中不精确,并讨论了完善确切类别结构的方法,以使张量产品函数精确。
We explain why the naive definition of a natural exact category structure on complete, separated topological vector spaces with linear topology fails. In particular, contrary to arXiv:0711.2527, the category of such topological vector spaces is not quasi-abelian. We present a corrected definition of exact category structure which works OK. Then we explain that the corrected definition still has a shortcoming in that a natural tensor product functor is not exact in it, and discuss ways to refine the exact category structure so as to make the tensor product functors exact.
