WebApr 8, 2024 · If the sets A A and B B are of the same cardinality, then there exists a bijection f:A\to B f: A → B. Since each bijection is an injection, f f is an injection, and therefore A \leq B ∣A∣ ≤ ∣B∣. The inverse function f^ {-1}:B\to A f −1: B → A is a bijection as well. Consequently, f^ {-1} f −1 is an injection. WebIf A and B are sets,and the intersection of A and B is equal to A, then the elements in A are in both the set A and B. Therefore, the set of A is a subset of B since all the elements are contained in the interesection of sets A and B are equal to A.

WebAn empty set is defined as a set with no elements. We want to show there is just one empty set; only one set that has no elements. Then we can refer to it as "the" empty set. Proof. Suppose $E_1$ and $E_2$ are empty sets, that is, they each have no elements. From Theorem 4.2.2, since $E_1$ has no elements, $E_1 \subseteq E_2.$
