David Till - Böcker

This volume contains the papers presented at the 6th Refinement Workshop which was held in London from 5 - 7 January 1994. The theme of the workshop was "the theory and practice of formal software development", and papers with industrial relevance were particularly encouraged. The papers address both the formal mathematical infrastructure of methods, and the practical application of formal development methods in commerce and industry. Among the specific topics covered are the formal development of authentication protocols, operation semantics with read and write frames, and the testing and safety analysis of abstract machine specifications. This volume will be of interest to academic and industrial researchers, postgraduate students, and research-oriented developers in the computer industry. The proceedings of the previous three Refinement Workshops are also available in the series.

This book constitutes the refereed proceedings of the 10th International Conference of Z Users, ZUM'97, held in Reading, UK, in April 1997.The volume presents 18 revised full papers together with three invited presentations by internationally leading experts. The papers are organized into topical sections on real-time systems, tools, logic, system development, reactive systems, refinement, and applications. Also a select Z bibliography by Jonathan Bowen is added. All in all, the book competently reports the state-of-the-art in research and advanced applications of the Z notation.
