建构系统的逻辑基础
A logical basis for constructive systems
摘要：
这项工作致力于可计算性逻辑（CoL）-哲学/数学平台和长期项目，用于在其底层语义中用可计算性取代真理之后重新开发经典逻辑（见http：//www.cis.upenn.edu/paggiorgi/cl.html）。本文阐述了CoL框架的一些基本复杂性理论。然后证明了演绎系统CL 12关于CoL语义的可靠性和完备性，包括后者基于多项式时间可计算性而不是原则上可计算性的版本。CL 12是一个微积分系统，其中一个变量的含义直观上可以被描述为“后继变量可以在算法上还原为先行变量”，并且其中公式是由谓词字母、函数字母、变量、常数、恒等式、否定式、平行和选择连接词以及盲量词和选择量词构建的。一个案例是CL 12是一个足够的逻辑基础建设性的应用理论，包括复杂性导向的。
英文摘要：
The work is devoted to Computability Logic (CoL) -- the philosophical/mathematical platform and long-term project for redeveloping classical logic after replacing truth} by computability in its underlying semantics (see http://www.cis.upenn.edu/~giorgi/cl.html). This article elaborates some basic complexity theory for the CoL framework. Then it proves soundness and completeness for the deductive system CL12 with respect to the semantics of CoL, including the version of the latter based on polynomial time computability instead of computability-in-principle. CL12 is a sequent calculus system, where the meaning of a sequent intuitively can be characterized as "the succedent is algorithmically reducible to the antecedent", and where formulas are built from predicate letters, function letters, variables, constants, identity, negation, parallel and choice connectives, and blind and choice quantifiers. A case is made that CL12 is an adequate logical basis for constructive applied theories, including complexity-oriented ones.
