Python package that provides an interface to work with classical propositional and first-order logic, based on my solutions to the textbook Mathematical Logic Through Python by Nisan and Gonczarowski ...

Abstract: We introduce a multi-type display calculus for Propositional Dynamic Logic (PDL). This calculus is complete w.r.t. PDL, and enjoys Belnap-style cut-elimination and subformula property.

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 ...

The classical propositional calculus (zero-order logic, classical propositional logic), is the most fundamental two-valued logical system. In this paper we present a proof of inconsistency of the ...

The Journal of Symbolic Logic (JSL) was founded in 1936 and it has become the leading research journal in the field. It is issued quarterly. Volume 71, being published during 2006, will consist of ...

Studia Logica publishes original papers on various logical systems, which utilize methods of contemporary formal logic (those of algebra, model theory, proof theory, etc.). More specifically, Studia ...

ABSTRACT: From fundamental concepts of the Paraconsistent Annotated Logic with annotation of two values (PAL2v), whose main feature is to be capable of treating contradictory information, was created ...

🧠💡 Web app to calculate everything related to propositional-calculus. Made for myself to pass TZI subject at Mendel University, but shared for everyone else for free to use it as well!

A review is presented of the correspondence existing in both classical bivalent logic (BL) and canonical fuzzy logic (CFL) between each law or tautology in propositional calculus and a law in set ...
