Myhillnerode relation induction on y

WebThe Myhill-Nerode Theorem says the following three statements are equivalent: 1) The set L, a subset of Sigma star, is accepted by a DFA. (We know this means L is a regular language.) 2) L is the union of some of the equivalence classes of a right invariant (with respect to concatenation) equivalence relation of finite index. Web21 mrt. 2024 · To summarize, a relation < without infinite descending chains gives us the following induction principle: Suppose that for every x ∈ A we have ( ∀ y < x. ϕ ( y)) ⇒ ϕ ( x). Then ∀ z ∈ A. ϕ ( z). The descending chain condition is useful for figuring out whether induction is valid.
