| Outline of Final Research Achievements |
We have developed dynamic modal propositional logic that can capture how utterances change epistemic states of agents and deontic structures of the situation. It enables us to analyze the functions of truth-apt utterances (assertions) and non-truth-apt utterances (commands, promises, requests) in a uniform framework. We have also developed a version of modal predicate logic called ``Dynamified Term-Sequence-Deontic Logic’’ and thereby opened a way to further research.
We have also developed logics and AI applications that deal with dynamic changes of knowledge and attitudes of people involved in a law court as well as a logic that deals with mutual knowledge of people with bounds of cognitive abilities from the point of view of bounded rationality in economics. Moreover, we have also developed a new socioeconomic thought for a small and narrow world with various different cultures from the same point of view of bounded rationality.
