(1)子集:一般地,對(duì)于兩個(gè)集合A與B,如果集合A的任何

個(gè)元素都是集合B的元素,我們就說(shuō)集合A包含于集

合B,或集合B包含集合A

記作: ,AB或BA 

讀作:A包含于B或B包含A

      當(dāng)集合A不包含于集合B,或集合B不包含集合A時(shí),則記

作AB或BA

注:有兩種可能

(1)A是B的一部分,;(2)A與B是同一集合

(2)集合相等:一般地,對(duì)于兩個(gè)集合A與B,如果集合A的任何一個(gè)元素都是集合B的元素,同時(shí)集合B的任何一個(gè)元素都是集合A的元素,我們就說(shuō)集合A等于集合B,記作A=B

(3)真子集:對(duì)于兩個(gè)集合A與B,如果,并且,我們就說(shuō)集合A是集合B的真子集,記作:AB或BA, 讀作A真包含于B或B真包含A

(4)子集與真子集符號(hào)的方向

(5)空集是任何集合的子集ΦA

空集是任何非空集合的真子集ΦA  若A≠Φ,則ΦA

任何一個(gè)集合是它本身的子集

(6)易混符號(hào)

①“”與“”:元素與集合之間是屬于關(guān)系;集合與集合之間是包含關(guān)系ΦR,{1}{1,2,3}

②{0}與Φ:{0}是含有一個(gè)元素0的集合,Φ是不含任何元素的集合

    如 Φ{0}不能寫(xiě)成Φ={0},Φ∈{0}

(7)含n個(gè)元素的集合的所有子集的個(gè)數(shù)是,所有真
