Also known as set intersection, intersection of sets

数学ないし集合論の用語

AI overview

An intersection in set theory is the collection of elements that belong to two or more sets at the same time. Understanding intersections is useful because it helps identify what different groups have in common, which is fundamental to solving problems involving overlapping categories or shared properties.

数学において集合族の共通部分(きょうつうぶぶん、英: intersection)とは、与えられた集合の集まり(族)全てに共通に含まれる元を全て含み、それ以外の元は含まない集合のことである。共通集合(きょうつうしゅうごう)、交叉(こうさ、交差)、交わり(まじわり、meet)、積集合(せきしゅうごう)、積(せき)などとも呼ばれる。ただし、積集合は直積集合の意味で用いられることが多い。
