Abstract
The paper considers term-modal logics and introduces some decidable fragments thereof. In particular, two fragments will be introduced: one that simulates monotone non-normal logics and another one that simulates normal multi-agent epistemic logics with quantification over groups of agents. These logics are defined semantically. Then, each of them is proof-theoretically characterized by a labelled calculus with good structural properties. Finally, we prove that each fragment considered is decidable, and we characterize the complexity of the validity problem for some of them.
Thanks are due to three anonymous referees and to the audience at EUMAS 2017, especially to Valentin Goranko, for helpful comments.
