WebMoore [7]. Inasmuch as Rabin-Scott [9] adopt this notion, too, it is con-venient to refer to [9] for various results presumed here. In particular, Kleene's theorem [5, Theorems 3, 5] is used in the form in which it appears in [9]. It is often perspicacious to view regular expressions, and this notion is used in the sense of [3]. Webtheorem: Theorem 3.1 If L⊆Σ ∗is regular, then ∂ uL is regular for all strings u ∈ Σ . Proof We start by showing that for any a ∈ Σ, the language ∂ aL is regular. Let Q,q 0,F,δ be a DFA that accepts the regular language L. Then we can construct a DFA that recognises ∂ aL as follows: if δ(q 0,a) is defined, then Q,δ(q 0,a),F ...

WebWe establish a Kleene theorem that shows the equivalence of the formalisms and states precise correspondence of flat rae and simple availability automata. For these automata, … WebWe can now state the basic theorem upon which the method relies. This theorem is a strengthened version of the original Rabin-Scott theorem [4].

WebProof of the Rabin-Scott Theorem. We already saw in the last section that every language which can be recognized by a DFA can also be recognized by an NFA. To complete the proof of the Rabin-Scott Theorem, we need to establish the other, far less trivial, direction. … WebTHEOREM 1 (Rabin and Scott, 1959).
