奇点三角化范畴的形式完备化与幂等完备化

Formal completions and idempotent completions of triangulated categories of singularities

Dmitri Orlov

摘要:

本文的主要目的是证明两个方案的三角化奇点范畴的幂等完备化是等价的,如果这些方案沿奇点的形式完备化是同构的。我们还讨论了稠密子范畴上的Kesason定理以及它与负K-理论的关系。

英文摘要:

The main goal of this paper is to prove that the idempotent completions of the triangulated categories of singularities of two schemes are equivalent if the formal completions of these schemes along singularities are isomorphic. We also discuss Thomason theorem on dense subcategories and a relation to the negative K-theory.
