TL;DR: Knowledge in Flux presents a theory of rational changes of belief, focusing particularly on revisions that occur when the agent receives new information that is inconsistent with the present epistemic state.

TL;DR: This book provides various logics to support formal specifications of multi-agent systems, including proof systems, and discusses various results on the expressive power of the logics presented.
Abstract: Dynamic Epistemic Logic is the logic of knowledge change. This is not about one logical system, but about a whole family of logics that allows us to specify static and dynamic aspects of multi-agent systems. This book provides various logics to support such formal specifications, including proof systems. Concrete examples and epistemic puzzles enliven the exposition. The book also contains exercises including answers and is eminently suitable for graduate courses in logic. A sweeping chapter-wise outline of the content of this book is the following. The chapter 'Introduction' informs the reader about the history of the subject, and its relation to other disciplines. 'Epistemic Logic' is an overview of multi-agent epistemic logic - the logic of knowledge - including modal operators for groups, such as general and common knowledge. 'Belief Revision' is an overview on how to model belief revision, both in the 'traditional' way and in a dynamic epistemic setting. 'Public Announcements' is a detailed and comprehensive introduction into the logic of knowledge to which dynamic operators for truthful public announcement are added. Many interesting applications are also presented in this chapter: a form of cryptography for ideal agents also known as 'the russian cards problem', the sum-and-product riddle, etc. 'Epistemic Actions' introduces a generalization of public announcement logic to more complex epistemic actions. A different perspective on that matter is independently presented in 'Action Models'. 'Completeness' gives details on the completeness proof for the logics introduced in 'Epistemic Logic', 'Public Announcements', and 'Action Models'. 'Expressivity' discusses various results on the expressive power of the logics presented.

TL;DR: Belief revision is a topic of much interest in theoretical computer science and logic, and it forms a central problem in research into artificial intelligence as mentioned in this paper, which addresses the problem of updating a database of knowledge in the light of new information and what to do in the case where new information is in conflict with something that was previously held to be true.
Abstract: From the Publisher: Belief revision is a topic of much interest in theoretical computer science and logic, and it forms a central problem in research into artificial intelligence. In simplest terms it addresses the problem of updating a database of knowledge in the light of new information and what to do in the case where new information is in conflict with something that was previously held to be true. The problem is central to the study of artificial intelligence, because an intelligent system should be able to accomodate all such cases. This book contains a collection of up-to-date research articles on belief revision and an introductory chapter that presents a survey of current research in the area and the fundamentals of the theory.
