Degree-preserving Godel logics with an involution: intermediate logics and (ideal) paraconsistency
M. E. Coniglio, F. Esteva, J. Gispert +1
In this paper we study intermediate logics between the degree preserving companion of Godel fuzzy logic with an involution and classical propositional logic CPL, as well as the int…
Axiomatizing logics of fuzzy preferences using graded modalities
Amanda Vidal, Francesc Esteva, Lluis Godo
The aim of this paper is to propose a many-valued modal framework to formalize reasoning with both graded preferences and propositions, in the style of van Benthem et al.'s classic…
Possibilistic semantics for a modal KD45 extension of Gödel fuzzy logic
Félix Bou, Francesc Esteva, Lluís Godo +1
In this paper we provide a simplified semantics for the logic KD45(G), i.e. the many-valued Gödel counterpart of the classical modal logic KD45. More precisely, we characterize KD4…
On Modal Logics for Qualitative Possibility in a Fuzzy Setting
Petr Hajek, Dagmar Harmancová, Francesc Esteva +2
Within the possibilistic approach to uncertainty modeling, the paper presents a modal logical system to reason about qualitative (comparative) statements of the possibility (and ne…
