Fi92a, Fi92b}of Fitting where the author defines a modal system over a logic of a finite Heyting algebragive a complete axiomatization of them. In its late paper Fitting justify it in a very nice an elegant semantics based on a multi-agent system each one using classical logichaving a preference relation. He defined the modal operators based on semanticshis definitions is the ones used in later papers on the topic as generalizations modal operators on many-valued systems based on Kripke semantics (with many-valued worldsmany-valued accessibility relations). In these approaches Modal many-valued language is built taking the language of the many-valued logic $(\land, \lor, &, \to_&, \neg_&, 0, 1)$ plus at least one the usual modal operators (necessity $\Box$possibility $\Diamond$)its semantic is defined by generalized Kripke models taking many-valued evaluation in each world $w \in W$many-valued accessibility relations $S: W \times W \to [0,1]$. The evaluation of modal operators are given (following Fitting \cite {Fi92a, Fi92b}) by \begin{itemize}\item $V ( \Box \varphi, w ) = {\displaystyle \bigwedge}\{ R(w,w') \to V(\varphi,w'): w' \in W \}$. \item $V ( \Diamond \varphi, w ) = {\displaystyle \bigvee}\{ R(w,w') & V(\varphi,w'): w' \in W \}$. \end{itemize}There are different attemptsapproaches to motivatestudy modal logic formalisms based on Kripke semantics to the many-valued setting. Roughly speaking we can classify the approaches in three groups depending how the corresponding Kripke frames look like, in the sense of how many-valuedness affects the worldsthe accesibility relations. Next we describe these three groupscomment about our work in each of them. A first group (see e.g. \cite{ChFr92, EsGaGoRo97,Su97}) is formed by those logical systems whose class of Kripke frames are such that their {\em worlds are classical}(i.e. they follow the rules of classical logic) but their {\em accessibility relations are many-valued; Modalities and many-valued: modeling uncertainty measures and similarity-based reasoning and application to Fuzzy description Logics .. 2010.  [PDF]  [BibTeX]
