In Propositional Calculus, each atomic symbol (P, Q, etc.) denotes a proposition of some complexity. In Propositional Calculus, we cannot access the components of an individual assertion, limiting our ...

ABSTRACT: In the XII Latin American Symposium on Mathematical Logic we presented a work introducing a Hilbert-style propositional calculus called four-valued Monteiro propositional calculus. This ...

Automated theorem prover for propositional logic which uses sequent calculus. Written in MAXIMA. As a research assistant in Tampere University I was tasked with creating moodle exercises using the ...

A presentation is provided of a structural approach for the concur rent teaching of introductory propositional calculus and set theory. The existence of isomorphism is shown between each law (or ...

where ---> and <---> are meant to be the traditional arrows denoting logical implication and logical equivalence. If you don't know propositional calculus, we'll say just a few things to help ease ...

Abstract: Residuated fuzzy logic calculi are related to continuous t-norms which are used as truth functions for the conjunction connective, and their residua as truth function for the implication. In ...

Abstract: We study predicate logic that is interpreted in Kripke models similarly to intuitionistic logic except that the accessibility relation of each model is not necessarily reflexive. Unlike in ...

ABSTRACT: The BCK/BCI/BCH-algebras finds general algebra system than Boolean algebras system. This paper presents a novel class of algebras of type (2, 0) called BCL-algebras. We found the ...
