Abstract

Networks of parallel language processors form a special type of grammar systems where derivation steps in the mode of L systems and communication steps alternate. We prove that, given an arbitrary system, an equivalent system with at most three components can be constructed. This improves a result of [2]. Furthermore we consider the function f(m) which gives the number of words generated in m steps. We relate this function to growth functions of D0L systems and prove the undecidability of the equivalence with respect to this function.
