Pseudo-intersection : ウィキペディア英語版 | Pseudo-intersection In mathematical set theory, a pseudo-intersection of a family of sets is an infinite set ''S'' such that each element of the family contains all but a finite number of elements of ''S''. The pseudo-intersection number, sometimes denoted by the fraktur letter 𝔭, is the smallest size of a family of infinite subsets of the natural numbers that has the strong finite intersection property but has no pseudo-intersection. ==References==
