有向族中的标准林

Canonical forests in directed families

Joseph Flenner, Vincent Guingona

摘要:

给出了有向集族中可构造集的表示的两个唯一性结果。在不可包装的情况下,瑞士奶酪的分解是独特的。在可包装的情况下,他们不是唯一的,但承认一个准序下的最小分解是唯一的。这两种情况导致VC-极小和准VC-极小理论的一维消除。

英文摘要:

Two uniqueness results on representations of sets constructible in a directed family of sets are given. In the unpackable case, swiss cheese decompositions are unique. In the packable case, they are not unique but admit a quasi-ordering under which the minimal decomposition is unique. Both cases lead to a one-dimensional elimination of imaginaries in VC-minimal and quasi-VC-minimal theories.
