WebWeighted Variable Automata over Infinite Alphabets Web1 Kleene’s Fixpoint Theorem Deﬁnition (Scott Continuity). A function F from U to U is said to be Scott-continuous if for every chain X1 X2 ::: we have F„ ∪ iXi” ∪ F„Xi”. It is not hard to show that if F is Scott continuous, then it is also monotonic—that is, X Y implies F„X” F„Y”. The proof of this fact is left as an ...
