Chapter1.Propositionallogic(命题逻辑)1.1PropositionsandConnectives 人的思维过程:概念判断推理 正确的思维:概念清楚,判断正确,推理合乎逻辑。人们是通过各种各样的学习(理论学习和从实践中学习)来掌握许多概念和判断。而形式逻辑主要是研究推理的。推理:是由若干个已知的判断...

Consistency, completeness and decidability for both classical and intuitionistic systems are given provided some simple conditions on the formation of propositional letters are satisfied. We describe an application to PROLOG programming in the context of databases....
we axiomatize the immediate predecessor of the full classical propositional calculus, and then establish the following main results: connectives c (implication), k (and), n (not), are independent in any intermediate propositional logic; quantifiers a (for all), e (there exists), are independent...
Featherweight OCL -- A study for the consistent semantics of OCL 2.3 in HOL At its origins, OCL was conceived as a strict semantics for undefinedness, with the exception of the logical connectives of type Boolean that constitute a three-valued propositional logic. Recent versions of the OCL st...

Probabilistic logicunreliable connectivesarrow and turnstile interpolationsArrow and turnstile interpolations are investigated in UCL [introduced by Sernadas et al. (J Logic Comput, 2013)], a logic that is a complete extension of classical propositional logic for reasoning about connectives that only ...
