Linking Theories of Concurrency Unu-iist and Unu-iist Reports Linking Theories of Concurrency

the governments of the People's Republic of China and Portugal through a contribution to the UNU Endownment Fund. As well as providing two-thirds of the endownment fund, the Macau authorities also supply UNU-IIST with its office premises and furniture and subsidise fellow accommodation. The mission of UNU-IIST is to assist developing countries in the application and development of software technology. UNU-IIST contributes through its programmatic activities: 1. Advanced development projects, in which software techniques supported by tools are applied, 2. Research projects, in which new techniques for software development are investigated, 3. Curriculum development projects, in which courses of software technology for universities in developing countries are developed, 4. University development projects, which complement the curriculum development projects by aiming to strengthen all aspects of computer science teaching in universities in developing countries, 5. Schools and Courses, which typically teach advanced software development techniques, 6. Events, in which conferences and workshops are organised or supported by UNU-IIST, and 7. Dissemination, in which UNU-IIST regularly distributes to developing countries information on international progress of software technology. Fellows, who are young scientists and engineers from developing countries, are invited to actively participate in all these projects. By doing the projects they are trained. At present, the technical focus of UNU-IIST is on formal methods for software development. UNU-IIST is an internationally recognised center in the area of formal methods. However, no software technique is universally applicable. We are prepared to choose complementary techniques for our projects, if necessary. UNU-IIST produces a report series. Reports are either Research R , Technical T , Compendia C or Administrative A. They are records of UNU-IIST activities and research and development achievements. Many of the reports are also published in conference proceedings and journals. if you would like to know more about UNU-IIST and its report series. Abstract We construct a Galois connection between the theories that underlie CCS [7] and CSP [4]. It projects the complete transition system for CCS onto exactly the subset that satisfies the healthiness conditions of CSP. The construction applies to several varieties of both calculi: CCS with strong, weak or barbed simulation, and CSP with trace refinement or failures refinement, or failures/divergence. We suggest the challenge of linking other theories of concurrency by Galois connection. He Jifeng is a senior research-fellow of UNU/IIST. He is also a professor of computer science at the Software Engineering Institute of East China Normal …
