The paper presents syntax, semantics, and monitoring algorithms for respectively propositional and first-order temporal log- ics. In propositional logics the observed events in the execution trace are rep- rese

We have chosen the field of propositional logic to investigate the use of MERs for two reasons. First, this topic is not part of the German school curriculum but is considered essential in the course of university education in the study of mathematics. Therefore, this topic is introduced to ...
Propositional/First-Order LogicCMSC Fall
Logic is a system for rational enquiry and is founded on axioms and inference rules for reasoning. Modern mathematical logic dates back to the works of Frege and Peano late in the 19th century. Examples of logic include classical propositional logic , first-order logic , modal logics and ...
