Nets, Terms and Formulas: Three Views of Concurrent Processes and their Relationship

The author presents a theory whereby nets, terms and formulas represent concurrent process at three levels of abstractions: Petri nets are used to describe all details of the operational machine behavior of processes. Algebraic process terms such as Calculus of Communicating Systems (CCS) or Communicating Sequential Processes (CSP) two of the main models for parallel programming, are used to describe the architecture of processes, i.e. how they can be composed from subprocesses. Logical for...
