Abstract

To introduce a temporal dimension to a belief logic, we consider a powerful technique called fibring for combining belief logics and temporal logics. In a fibred belief logic, both temporal operators and belief operators are treated equally. This paper in particular discusses a combination of a belief logic called Typed-Modal Logic with a linear-time temporal logic. We show that, in the resulting logic, we can specify and reason about not only agent beliefs but also the timing properties of a system. With this logical system one is able to build theories of trust for the description of, and reasoning about, multi-agent systems.
