摘要
In this paper we investigate several decision problems for parallel communicating grammar systems: the enabling, circularity, centralizing, conflict-freeness, boundedness, membership, equivalence, inclusion, emptiness and finiteness problems. The first five problems are shown to be decidable for context-free PCS's but undecidable for the context-sensitive case. The last five problems are only studied for the context-sensitive case and they are shown to be undecidable.
