- W2014568148 abstract "We show that there exists an ultrafilter U in the set N of natural numbers such that the cofinality of the U-ultrapower N N/U equals cof(d), where d is the minimal cardinality of a dominating subfamily of N N. More over, the coinitiality of the family of finite-to-one functions in this ultrapower is also cof(d). If c=d, then U may be taken to be a P-point" @default.
