团队逻辑的可能与不可能条件句

Possible and impossible conditionals for team logics

University of Helsinki(赫尔辛基大学);Utrecht University(乌得勒支大学)

Fausto Barbero, Fan Yang

AI总结:

本文研究基于团队语义的逻辑能否添加满足最小要求(如保持逻辑封闭性、肯定前件和演绎定理)的条件句,发现向下或向上封闭的逻辑存在这样的条件句,而并封闭、凸或交封闭的逻辑通常不存在。

摘要:

我们研究基于团队语义的逻辑能否添加满足最小要求的条件句,例如保持逻辑的封闭性、肯定前件和演绎定理。我们证明,对于向下或向上封闭的逻辑,存在这样的良态条件句,但对于并封闭、凸或交封闭的逻辑,通常不存在。我们还简要研究了满足较弱要求的条件句。

英文摘要:

We study whether a logic based on team semantics can be enriched with a conditional satisfying minimal requirements, such as preservation of the closure property of the logic, Modus Ponens, and the Deduction Theorem. We show that such well-behaved conditionals exist for downward or upward closed logics, but do not typically exist for union closed, convex or intersection closed logics. We also briefly investigate conditionals satisfying weaker requirements.
