It follows that α −→ t. This proves the inclusion. Consider now the converse inclusion L(G, α) ⊂ L(G , U ) α∈U This means that, for each word w ∈ L(G, α), there exists a set U containing α such that w ∈ L(G , U ). We shall in fact prove the following, slightly more general property. Let m ∈ ∗ (V ∪ A)∗ . If α −→ m, then for every set M containing m, there exists a set U ∗ containing α such that U −→ m. Assume indeed that α −→ m. If = 1, choose any “big word” M containing m and let U = {γ | M ∈ Rγ }.

Then agyd¯ a ∈ [X]. Consequently agzd¯ a ∈ [X], showing that rqs ∈ RX,a , and therefore p ≈ q. This shows that to each equivalence class of ≡L intersecting D∗ corresponds one equivalence class of RX,a . Since there are finitely many of the former, there are finitely may of the second, and RX,a is regular. Conversely, assume now that L is balanced. Then it is of course well-formed. Consider a codeterministic balanced grammar G generating L. Let u ∈ D∗ be a Dyck word that is a factor of some word in L, and set u = v1 · · · vn , with v1 , .

The grammar X0 → Y a¯ a X → aY a ¯ | aa Y → aX¯ aa ¯aa¯ a | aY a ¯a ¯a ¯aX¯ a generates a balanced language. It was used by Knuth ([6]) to demonstrate how his algorithm for the effective construction of a balanced grammar works. 2 Decision Problems In this section, we state two decidability results. There are other decision problems that will be considered later. The following result was proved in [1]. It will be used later. 10. Given a context-free language L over an alphabet A ∪ A, ¯ decidable whether L is a subset of the set DA of Dyck primes over A ∪ A.
