Abstract
We analyze the effect of the degree of isolation ε of a cut point on the number of states P(U, ε) of a probabilistic automaton representing the language U. We give an example of a language Un consisting of words of length n such that there exist numbers ε′<ε for which P(Un, ε′)/P(Un, ε)→0 as n→∞.
