Neurotransmitters and peptides: whispered secrets and public announcements

How Your Brain Cells Talk to Each Other—Whispered Secrets and Public Announcements

Imagine that you want to tell your friends something new; you could whisper it into their ears or shout it out loud. This is rather like two forms of communication that occur within your brain. Your brain contains billions of nerve cells, called neurons, which make a very large number of connections with specialized parts of other neurons, called dendrites, to form networks. Neurons have been t...

Public Announcements, Topology and Paraconsistency

In this paper, we discuss public announcement logic in topological context. Then, as an interesting application, we consider public announcement logic in a paraconsistent topological model.

Public Announcements and Belief Expansion

In this paper we study the relation between two approaches to information change: Dynamic Epistemic Logic and Belief Revision. One of the main differences between these approaches is that higher-order information plays an important role in the field of Dynamic Epistemic Logic, whereas it does not feature in Belief Revision. In this paper we study to which extent public announcements (a particul...

Fully Arbitrary Public Announcements

Total Public Announcements

We present a dynamic epistemic logic for knowledge change of rational agents. Existing approaches only deal with partial public announcements, that means an announcement may lead to an inconsistent state. We introduce an extension of the multi-modal logic S5n featuring total public announcements where an update cannot result in an inconsistency. We also study total public announcements in the c...
