反思原则、命题证明系统和理论

Reflection principles, propositional proof systems, and theories

Pavel Pudlák

摘要:

反射原理是这样的陈述,即如果一个句子是可证明的,那么它就是真的。反射原理已经被研究用于一阶理论,但它们在命题证明复杂性中也起着重要作用。在本文中,我们将重新审视一些结果的反射原则的命题证明系统使用更精细的规模的反射原则。我们将使用的结果,证明下界的决议证明是困难的决议。这首先出现在最近的文章Atserias和穆勒作为一个关键引理,并推广和简化了一些衍生文件。我们也将调查一些结果有关的算术理论和证明系统与他们有关。我们将展示一个关于有限一致性陈述的证明复杂性的猜想和一个关于与理论相关的证明系统的陈述之间的联系。

英文摘要:

The reflection principle is the statement that if a sentence is provable then it is true. Reflection principles have been studied for first-order theories, but they also play an important role in propositional proof complexity. In this paper we will revisit some results about the reflection principles for propositional proofs systems using a finer scale of reflection principles. We will use the result that proving lower bounds on Resolution proofs is hard in Resolution. This appeared first in the recent article of Atserias and Müller as a key lemma and was generalized and simplified in some spin-off papers. We will also survey some results about arithmetical theories and proof systems associated with them. We will show a connection between a conjecture about proof complexity of finite consistency statements and a statement about proof systems associated with a theory.
