- Interval Temporal Logics: a Journey by Dario Della Monica, Valentin Goranko, Angelo Montanari and Guido Sciavicco. [PDF]
- Assertional and Behavioral approaches to concurrency by Uri Abraham. [PDF]
The second contribution is a a piece by Uri Abraham in which he compares two proofs of the mutual-exclusion property for the well known algorithm by Peterson: an assertional proof and a behavioural one. The article outlines a framework within which the behavioural approach can be formalized in a way that retains the intuitive content of the behavioural reasoning.
This is my last issue as editor of the Concurrency Column. I have been editing the column for the last eight years, and I feel that it is time to step down. The column will benefit greatly from a fresh perspective on the world of concurrency theory and I look forward to reading the pieces that will appear in future issues.I thank the contributors to the Concurrency Column over the last eight years and all my readers.
