Sacks property
text:
In mathematical set theory, the Sacks property holds between two models of Zermelo–Fraenkel set theory if they are not "too dissimilar" in the following sense. For M and N transitive models of set theory, N is said to have the Sacks property over M if and only if for every function g ∈ M mapping ω to ω ∖ { 0 } such that g diverges to infinity, and every function f ∈ N mapping ω to ω there is a tree T ∈ M such that for every n the n t h level of T has cardinality at most g and f is a branch of T
