This paper considers two logics. The first one, $\mathbf {K}\mathsf {G} _\mathsf {inv} $, is an expansion of the G\" odel modal logic $\mathbf {K}\mathsf {G} $ with the involutive negation …
We present the axiomatisation of the fuzzy bi-G\"{o} del modal logic (formulated in the language containing $\triangle $ and treating the coimplication as a defined connective) and …
This dissertation is devoted to the study of fuzzy modal logics that formalise (paraconsistent) reasoning about uncertainty. The understanding of 'uncertain information (data)'here …
