WitrynaConsistency and completeness in arithmetic and set theory. In theories of arithmetic, such as Peano arithmetic, there is an intricate relationship between the consistency of the theory and its completeness.A theory is complete if, for every formula φ in its language, at least one of φ or ¬φ is a logical consequence of the theory. WitrynaA general framework of consistency checking and correcting of geographical database in vector format is proposed.
