 According to , during the entire evolution we have

with 1 − "p"3("t") changing from epoch to epoch, running through values in the interval from 0 to 1.The term ln Ω = ln ln (1/"t") increases monotonically; on the other hand, the term ln2(1 − "p"3) can assume large values (comparable with ln Ω) only when values of "p"3 very close to unity appear (i.e., very small |"p"1|).These are precisely the "dangerous" cases that disturb the regular course of evolution expressed by the recurrent relationships –.
