Graphical representation of covariant-contravariant modal formulae [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2011
Covariant-contravariant simulation is a combination of standard (covariant) simulation, its contravariant counterpart and bisimulation. We have previously studied its logical characterization by means of the covariant-contravariant modal logic. Moreover,

Computing Distances between Probabilistic Automata [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2011
We present relaxed notions of simulation and bisimulation on Probabilistic Automata (PA), that allow some error epsilon. When epsilon is zero we retrieve the usual notions of bisimulation and simulation on PAs.

Semantic Incompleteness of Liberman et al. (2020)’s Hilbert-style Systems for Term-modal Logics with Equality and Non-rigid Terms

open access: yesBulletin of the Section of Logic
In this paper, we prove the semantic incompleteness of some expansions of the Hilbert-style system for the minimal normal term-modal logic with equality and non-rigid terms that were proposed in Liberman et al.

Admissible Inference Rules and Semantic Property of Modal Logics

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2021
Firstly semantic property of nonstandart logics were described by formulas which are peculiar to studied a models in general, and do not take to consideration a variable conditions and a changing assumptions.

The Subject Term of Universal Proposition According to Ibn Sīnā and Fakhr al-Dīn al-Rāzī

open access: yesİslam Tetkikleri Dergisi, 2023
This article examines Ibn Sīnā’s (d. 428/1037) views on the subject term of universal categorical proposition as well the comments of his influential interpreter and critic Fakhr al-Dīn al-Rāzī (d. 606/1210) regarding this subject term.

Classical term-modal logics

open access: yesJournal of Logic and Computation, 2020
Abstract We introduce classical term-modal logics and argue that they are useful for modelling agent-relative notions of obligation, evidence and abilities, and their interaction with properties of and relations between the agents in question.

The evolution of the ideas of metaphysics and ontology

open access: yesИнтеллект. Инновации. Инвестиции, 2020
The categories of metaphysics and ontology in aspect of their evolution are considered in the article. At the beginning of the article, we are talking about the absence of the term «being» in ancient languages and its birth as a philosophical term ...

Reasoning with Rules and Rights: Term-Modal Deontic Logic

open access: yes, 2021
General obligations such as ‘every driver has to give way to a driver coming from the right’ are central in legal reasoning, but have been mostly overlooked in deontic logic. We claim that a simple extension of Standard Deontic Logic to the predicative level is insufficient to capture general obligations.

Dual-Context Calculi for Modal Logic [PDF]

open access: yes, 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
