Normal closure — The term normal closure is used in two senses in mathematics: In group theory, the normal closure of a subset of a group is the smallest normal subgroup that contains the subset; see conjugate closure. In field theory, the normal closure of an… … Wikipedia
Normal measure — In set theory, a normal measure is a measure on a measurable cardinal κ such that the equivalence class of the identity function on κ maps to κ itself in the ultrapower construction. Equivalently, if f:κ→κ is such that f(α)<α for most α<κ,… … Wikipedia
