A Characterisation of Open Bisimilarity using an Intuitionistic Modal Logic [PDF]

open access: yesLogical Methods in Computer Science, 2021
Open bisimilarity is defined for open process terms in which free variables may appear. The insight is, in order to characterise open bisimilarity, we move to the setting of intuitionistic modal logics. The intuitionistic modal logic introduced, called $\

A Real-Valued Modal Logic [PDF]

open access: yesLogical Methods in Computer Science, 2018
A many-valued modal logic is introduced that combines the usual Kripke frame semantics of the modal logic K with connectives interpreted locally at worlds by lattice and group operations over the real numbers.

STABLE MODAL LOGICS [PDF]

open access: yesThe Review of Symbolic Logic, 2018
AbstractStable logics are modal logics characterized by a class of frames closed under relation preserving images. These logics admit all filtrations. Since many basic modal systems such as K4 and S4 are not stable, we introduce the more general concept of an M-stable logic, where M is an arbitrary normal modal logic that admits some filtration.

SYMMETRIES IN MODAL LOGICS [PDF]

open access: yesThe Bulletin of Symbolic Logic, 2015
AbstractIn this paper we develop the theoretical foundations to exploit symmetries in modal logics. We generalize the notion of symmetries of propositional formulas in conjunctive normal form to modal formulas using the framework provided by coinductive modal models introduced in [5].

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 ...

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 ...

Dual characterizations for finite lattices via correspondence theory for monotone modal logic [PDF]

open access: yesJournal of Logic and Computation, 2014
We establish a formal connection between algorithmic correspondence theory and certain dual characterization results for finite lattices, similar to Nation's characterization of a hierarchy of pseudovarieties of finite lattices, progressively ...

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.

Complete Additivity and Modal Incompleteness [PDF]

open access: yes, 2019
In this paper, we tell a story about incompleteness in modal logic. The story weaves together a paper of van Benthem, `Syntactic aspects of modal incompleteness theorems,' and a longstanding open question: whether every normal modal logic can be ...

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.
