Abstract
We investigate the power of various types of synchronization in parall el communicating grammar systems. Systems without a universal clock (a pumping lemma is given for this case) proves in general to be weaker than the synchronized systems. Further synchronizing restrictions are introduced (added to the basic synchronization by a universal clock) a nd their effect on the generative capacity of grammar systems is exami ned.
