ATL+ is a variant of alternating-time temporal logic that does not have the expressive power of full ATL , but still allows for expressing some natural properties of agents. It ha...
This paper is the first in a series of three related papers on modal methods in interpretability logics and applications. In this first paper the fundaments are laid for later res...
We analyze extensive games as interactive process models, using modal languages plus matching notions of bisimulation as varieties of game equivalences. Our technical results show ...
Abstract. We present the first terminating tableau calculus for basic hybrid logic with the difference modality and converse modalities. The language under consideration is basic m...
Coalgebras provide a uniform framework for the semantics of a large class of (mostly non-normal) modal logics, including e.g. monotone modal logic, probabilistic and graded modal l...
