Nonexistence of Nonmolecular Generic Sets
Publications de l'Institut Mathématique, _N_S_36 (1984) no. 50, p. 29
Generic subsets of partially ordered sets play an important
role in giving significant examples of Zermelo-Fraenkel set-theoretical
models. The significance of these models lies in the fact that a
generic subset $G$ of a partially ordered set $P$, in general, does not
exist in a model $M$ in which $P$ exists. Thus, by adjoining $G$ to
$M$ an interesting extended model may ensue which has properties not
shared by $M$. Thus, in considering generic extensions of
set-theoretical models it is quite relevant to know whether or not a
generic subset of a partially ordered set $P$ exists in the same model
in which $P$ exists. In this paper, we give a necessary and sufficient
condition for $P$ to have a generic subset in the same model.
