On the Size Complexity of Non-Returning Context-Free PC Grammar Systems [PDF]
Improving the previously known best bound, we show that any recursively enumerable language can be generated with a non-returning parallel communicating (PC) grammar system having six context-free components.

On the power of parallel communicating grammar systems with right-linear components [PDF]
Summary: We settle here two problems concerning the generative power of parallel communicating grammar systems with right-linear components: (1) each linear language can be generated by a non-centralized returning system, (2) the family of languages generated by centralized returning systems is incomparable with the family of languages generated by non-

Poetic Judgement in Everyday Speech
Speaking is a highly conventional enterprise. But unusual usages are, nonetheless, frequently encountered. Some of these novelties fall flat, while others find favour, to the extent of entering common usage.

Some decision problems for parallel communicating grammar systems
AbstractIn 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.

On Parallel Communicating Grammar Systems and Correctness Preserving Restarting Automata [PDF]
This paper contributes to the study of Freely Rewriting Re-starting Automata (FRR-automata) and Parallel Communicating Grammar Systems (PCGS) as formalizations of the linguistic method of analysis by reduction . For PCGS we study two complexity measures called generation complexity and distribution complexity , and we prove that a PCGS *** , for which ...

Parallel communicating grammar systems with context-free components are Turing complete for any communication model [PDF]
Abstract Parallel Communicating Grammar Systems (PCGS) were introduced as a language-theoretic treatment of concurrent systems. A PCGS extends the concept of a grammar to a structure that consists of several grammars working in parallel, communicating with each other, and so contributing to the generation of strings.
