… . For a given class of languages, we say that it is Parikh-bounded if for any L in the class
there exists a bounded language L in the class with L ⊆ L and Φ(L) = Φ(L ). This property is …

Two-way Parikh automata

… , and then we apply a PSpace algorithm performing on-the-fly the one-way transformation
up to some bounded length. Finally, the emptiness problem for the intersection of n PA was …

Parikh-bounded languages

M Blattner, M Latteux - Automata, Languages and Programming: Eighth …, 1981 - Springer
… The central result in this paper is that if L is context-free it is also Parikh-bounded. Parikh's
theorem follows as a corollary. If L is not bounded but is a Parikh-bounded language closed …

The idea for the proof of the lemma is as follows. Suppose 𝑆𝑅𝜔 (A1) ∩ 𝑅𝑅𝜔 (A2) ≠ ∅ and let …

On the expressiveness of Parikh automata and related models
