Extensia lui δ la cuvinte<br />

ˆδ(q, a) = Cl(δ(Cl(q), a)),∀q ∈ Q,∀a ∈ Σ<br />

În cazul automatelor cu ǫ - tranziţii vom păstra notaţia ˆδ pentru<br />

extensie pentru că, în general, ˆδ(q,ǫ) ≠ δ(q,ǫ) <strong>şi</strong><br />

ˆδ(q, a) ≠ δ(q, a), a ∈ Σ.<br />

ˆδ(q, uv) = ˆδ(ˆδ(q, u), v), ∀q ∈ Q,∀u, v ∈ Σ ∗<br />
