权结构的中心是弱幂等完备范畴

The hearts of weight structures are the weakly idempotent complete categories

Mikhail V. Bondarko, Sergei V. Vostokov

摘要:

本文证明了作为权结构的心脏出现的加法范畴恰是弱幂等完备范畴,即所有分裂单态给出直和分解的范畴。给出了弱幂等完备性的几个等价条件(其中有些是全新的),并讨论了可加范畴的弱幂等完备性。

英文摘要:

In this note we prove that additive categories that occur as hearts of weight structures are precisely the weakly idempotent completecategories, that is, the categories where all split monomorphisms give direct sum decompositions. We also give several other conditions equivalent to weak idempotent completeness (some of them are completely new), and discuss weak idempotent completions of additive categories.
