张量三角范畴中的强生成元

Strong generators in tensor triangulated categories

Johan Steen, Greg Stevenson

摘要:

我们证明了在一个本质上小的刚性张量三角范畴中,不存在允许强生成元的真非零厚张量理想。这证明了,例如,范畴的完美复体在交换环没有非平凡幂等元有没有适当的非零厚子范畴是强生成的。

英文摘要:

We show that in an essentially small rigid tensor triangulated category with connected Balmer spectrum there are no proper non-zero thick tensor ideals admitting strong generators. This proves, for instance, that the category of perfect complexes over a commutative ring without non-trivial idempotents has no proper non-zero thick subcategories that are strongly generated.
