Indicative Conditionals and Dynamic Epistemic Logic [PDF]
Electronic Proceedings in Theoretical Computer Science, 2017 Recent ideas about epistemic modals and indicative conditionals in formal semantics have significant overlap with ideas in modal logic and dynamic epistemic logic.

Binary modal logic and unary modal logic
Logic Journal of the IGPL, 2023 Abstract Standard unary modal logic and binary modal logic, i.e. modal logic with one binary operator, are shown to be definitional extensions of one another when an additional axiom $U$ is added to the basic axiomatization of the binary side. This is a strengthening of our previous results.

Systematic Verification of the Modal Logic Cube in Isabelle/HOL [PDF]
Electronic Proceedings in Theoretical Computer Science, 2015 We present an automated verification of the well-known modal logic cube in Isabelle/HOL, in which we prove the inclusion relations between the cube's logics using automated reasoning tools. Prior work addresses this problem but without restriction to the

Modal‐type orthomodular logic [PDF]
Mathematical Logic Quarterly, 2009 AbstractIn this paper we enrich the orthomodular structure by adding a modal operator, following a physical motivation. A logical system is developed, obtaining algebraic completeness and completeness with respect to a Kripkestyle semantic founded on Baer*‐semigroups as in [22] (© 2009 WILEY‐VCH Verlag GmbH & Co.

Quantification of Modal Propositions in Traditional Logic [PDF]
Akofena: 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
Известия 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]
Journal 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 ...

Graphical Sequent Calculi for Modal Logics [PDF]
Electronic 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.

, 2020 The discussion about how to put together Gentzen's systems for classical and intuitionistic logic in a single unified system is back in fashion. Indeed, recently Prawitz and others have been discussing the so called Ecumenical Systems, where connectives from these logics can co-exist in peace.

The Logic of Khārijī Propositions [PDF]
حکمت 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.
