Satisfiability Problem in Interval FP-logic

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2023
The article investigates the interval modal logic, in which an action of the modal operator $\Diamond$ is limited by the boundaries of an interval. In addition, the language of modal logic is extended by the operator $D (\alpha, \beta)$, the truth of ...

The Logic of Khārijī Propositions [PDF]

open access: yesحکمت سینوی, 2023
There are two general methods for interpreting and analyzing khārijī and ḥaqīqī propositions: first, by analyzing them within a unified logic; second, by assigning separate logics to khārijī and ḥaqīqī propositions.

Quantification of Modal Propositions in Traditional Logic [PDF]

open access: yesAkofena
: Modal systems did not emerge until recently with Lewis Clarence, who raised the issue of strict implication. Although modal systems have evolved and diversified significantly since then, they remain loyal to his frameworks, as they are considered ...

Graphical Sequent Calculi for Modal Logics [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2017
The syntax of modal graphs is defined in terms of the continuous cut and broken cut following Charles Peirce's notation in the gamma part of his graphical logic of existential graphs.

Refinement modal logic

open access: yesInformation and Computation, 2014
In this paper we present {\em refinement modal logic}. A refinement is like a bisimulation, except that from the three relational requirements only `atoms' and `back' need to be satisfied. Our logic contains a new operator 'all' in addition to the standard modalities 'box' for each agent.

A basic epistemic logic and its algebraic model

open access: yesIntermaths, 2023
In this paper we propose an algebraic model for a modal epistemic logic. Although it is known the existence of algebraic models for modal logics, considering that there are so many different modal logics, so it is not usual to give an algebraic model ...

Dual-Context Calculi for Modal Logic [PDF]

open access: yesLogical Methods in Computer Science, 2020
We present natural deduction systems and associated modal lambda calculi for the necessity fragments of the normal modal logics K, T, K4, GL and S4. These systems are in the dual-context style: they feature two distinct zones of assumptions, one of which

Towards a Proof Theory of G\"odel Modal Logics [PDF]

open access: yesLogical Methods in Computer Science, 2011
Analytic proof calculi are introduced for box and diamond fragments of basic modal fuzzy logics that combine the Kripke semantics of modal logic K with the many-valued semantics of G\"odel logic.

Coherence in Modal Logic

open access: yesAdvances in Modal Logic, 2018
A variety is said to be coherent if the finitely generated subalgebras of its finitely presented members are also finitely presented. In a recent paper by the authors it was shown that coherence forms a key ingredient of the uniform deductive interpolation property for equational consequence in a variety, and a general criterion was given for the ...
