Tableau Systems for Epistemic Positional Logics

open access: yesBulletin of the Section of Logic, 2021
The goal of the article is twofold. The first one is to provide logics based on positional semantics which will be suitable for the analysis of epistemic modalities such as ‘agent ... knows/beliefs that ...’.

Belief as Willingness to Bet [PDF]

open access: yes, 2014
We investigate modal logics of high probability having two unary modal operators: an operator $K$ expressing probabilistic certainty and an operator $B$ expressing probability exceeding a fixed rational threshold $c\geq\frac 12$.

Probabilistic Justification Logic

open access: yesPhilosophies, 2018
Justification logics are constructive analogues of modal logics. They are often used as epistemic logics, particularly as models of evidentialist justification.

Dynamic Conflict Resolution Using Justification Based Reasoning [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2019
We study conflict situations that dynamically arise in traffic scenarios, where different agents try to achieve their set of goals and have to decide on what to do based on their local perception.

Categories for Dynamic Epistemic Logic [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2017
The primary goal of this paper is to recast the semantics of modal logic, and dynamic epistemic logic (DEL) in particular, in category-theoretic terms. We first review the category of relations and categories of Kripke frames, with particular emphasis ...

Propositional Logics Complexity and the Sub-Formula Property [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2015
In 1979 Richard Statman proved, using proof-theory, that the purely implicational fragment of Intuitionistic Logic (M-imply) is PSPACE-complete.

Knowability Relative to Information [PDF]

open access: yes, 2018
We present a formal semantics for epistemic logic, capturing the notion of knowability relative to information (KRI). Like Dretske, we move from the platitude that what an agent can know depends on her (empirical) information.

On the Possibility of a General Purge of Self-Reference

open access: yesAnálisis Filosófico, 2012
My aim in this paper is to gather some evident in favor of the view that a general purge of self-reference is possible. I do this by considering a modal-epistemic version of the Liar Paradox introduced by Roy Cook.

A simple logic for reasoning about incomplete knowledge [PDF]

open access: yes, 2014
International audienceThe semantics of modal logics for reasoning about belief or knowledge is often described in terms of accessibility relations, which is too expressive to account for mere epistemic states of an agent.
