Let L ⊂ Σ∗,T ⊂ Γ∗be two languages.We say that L is Mealy- reducible to T if and only if there exists a Mealy machine M = (Q,q0,Σ,Γ,δ,λ) such that for all w ∈ Σ∗ the condition w ∈ L if and only if OM (w) ∈ T holds. We use the symbol L M T to indicate that L is Mealy reducible to T. Most grammar classes are closed under Mealy reductions.
