WebMyhill-Nerode Theorem DEFINITION Let A be any language over Σ∗. We say that strings x and y in Σ∗ are indistinguish-able by A iff for every string z ∈ Σ∗ either both xz and yz are in A or both xz and yz are not in A. We write x ≡ A y in this case. Note that ≡ A is an equivalence relation. (Check this yourself.)
