Abstract
In formal epistemology, group knowledge is often modelled as the knowledge that the group would have if the agents shared all their individual knowledge. However, this interpretation does not account for relations between agents. In this work, we propose the notion of synergistic knowledge, which makes it possible to model those relationships. As examples, we investigate the use of consensus objects and the problem of the dining cryptographers. Moreover, we show that our logic can also be used to model certain aspects of information flow in networks.
