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.

Term Definable Classes of Boolean Functions and Frame Definability in Modal Logic [PDF]

open access: closedLogic Journal of IGPL, 2007
We establish a connection between term definability of Boolean functions and definability of finite modal frames. We introduce a bijective translation between functional terms and uniform degree-1 formulas and show that a class of Boolean functions is defined by functional terms if and only if the corresponding class of Scott-Montague frames is defined

Dynamic term-modal logic

open access: green, 2007
abstract. A first-order dynamic epistemic logic is developed where the names of the agents are also terms in the sense of first-order logic. Consequently one can quantify over epistemic modalities. Us- ing constructs from dynamic logic one can express many interesting concepts.

Formalizing Decisional and Operational Roles in Legal Contracts via Term-Modal Logic

open access: greenCEUR Workshop Proceedings
Translations of legal contracts into formal specifications that can be used for assisted reasoning are currently gaining considerable attention in AI and law. Yet, the conceptual intricacy of some of the normative notions involved in legal contracts continues to provide significant challenges to formalization; in accordance with this, there is a need ...

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 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 ...

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
