The area of coalgebra has emerged within theoretical computer science with a unifying claim: to be the mathematics of computational dynamics. It combines ideas from the theory of dynamical systems and from the theory of state-based computation. Although still in its infancy, it is an active area of research that generates wide interest. Written by one of the founders of the field, this book acts as the first mature and accessible introduction to coalgebra. It provides clear mathematical explanations, with many examples and exercises involving deterministic and non-deterministic automata, transition systems, streams, Markov chains and weighted automata. The theory is expressed in the language of category theory, which provides the right abstraction to make the similarity and duality between algebra and coalgebra explicit, and which the reader is introduced to in a hands-on manner. The book will be useful to mathematicians and (theoretical) computer scientists and will also be of interest to mathematical physicists, biologists and economists.

This study embarks on the intriguing quest for the origins of the Caribbean creole language Papiamentu. In the literature on the issue, widely diverging hypotheses have been advanced, but scholars have not come close to a consensus. The present study casts new and long-lasting light on the issue, putting forward compelling interdisciplinary evidence that Papiamentu is genetically related to the Portuguese-based creoles of the Cape Verde Islands, Guinea-Bissau, and Casamance (Senegal). Following the trans-Atlantic transfer of native speakers to Curacao in the latter half of the 17th century, the Portuguese-based proto-variety underwent a far-reaching process of relexification towards Spanish, affecting the basic vocabulary while leaving intact the original phonology, morphology, and syntax. Papiamentu is thus shown to constitute a case of 'language contact reduplicated' in that a creole underwent a second significant restructuring process (relexification). These explicit claims and their rigorous underpinning will set standards for both the study of Papiamentu and creole studies at large and will be received with great interest in the wider field of contact linguistics.

This book constitutes the proceedings of the 19th International Conference on Foundations of Software Science and Computation Structures, FOSSACS 2016, which took place in Eindhoven, The Netherlands, in April 2016, held as Part of the European Joint Conferences on Theory and Practice of Software, ETAPS 2016. The 31 full papers presented in this volume were carefully reviewed and selected from 85 submissions. They were organized in topical sections named: types; recursion and fixed-points; verification and program analysis; automata, logic, games; probabilistic and timed systems; proof theory and lambda calculus; algorithms for infinite systems; and monads.

Formal Methods for Open Object-Based Distributed Systems V brings together research in three important and related fields: * Formal methods; * Distributed systems; * Object-based technology. Such a convergence is representative of recent advances in the field of distributed systems, and provides links between several scientific and technological communities. The wide scope of topics covered in this volume range in subject from UML to object-based languages and calculi and security, and in approach from specification to case studies and verification. This volume comprises the proceedings of the Fifth International Conference on Formal Methods for Open Object-Based Distributed Systems (FMOODS 2002), which was sponsored by the International Federation for Information Processing (IFIP) and held in Enschede, The Netherlands in March 2002.
