Smolka %O ACM id. 242290 %N 4es %V 28 %D 1996 %T Concurrency: Theory and Practice %J ACM Computing Surveys (CSUR) - Special issue: position statements on strategic directions in computing research %X Concurrency theory is concerned with the modeling and verification of concurrent systems, while concurrency practice promulgates the application of concurrency theory to concurrent systems of practical interest. We assert that a strong interplay between concurrency theory and practice is essential for the continued development of both fields.
