WebEqual sets are defined as the sets that have the same cardinality and all equal elements. In other words, two or more sets are said to be equal sets if they have the same elements and the same number of elements. For example set A = {1, 2, 3, 4, 5} and B = {1, 2, 3, 4, 5}.

WebTwo sets S 1 and S 2 have the same cardinality if and only if there exists a one-to-one correspondence between them, i.e. a bijective map f: S 1 → S 2 . For example, if S 1 = { 2 , 4 , 6 } and S 2 = { 1 , 2 , 3 } then clearly ∣ S 1 ∣ = ∣ S 2 ∣ = 3 and a bijection between them is f : S 1 → S 2 , f ( n ) = n /2 . Web10 jan. 2014 · Either two sets have the same cardinality, or one has cardinality greater than the other set-theory order-theory 1,141 Solution 1 You say: The theorem implies that if there is no surjection of $A$ onto $B$ then there has to be an injection of $A$ into $B$.
WebEquivalent sets are sets that have the same cardinality. This means that the two sets have the same number of elements. Let’s take a look at some examples. Example 1: The sets {1, 2, 3} and {4, 5, 6} are equivalent because they both have three elements. Example 2: The sets {1, 2, 3} and {a, b, c} are equivalent because they both have three ...
Web28 okt. 2009 · Show that if A and B are sets with the same cardinality, then the power set of A and the power set of B have the same cardinality. Since A and B have the same cardinality there is a bijection between A and B. Therefore each element of A can be paired with each element of B.
