WebBasic Set Theory. Sets are well-determined collections that are completely characterized by their elements. Thus, two sets are equal if and only if they have exactly the same elements. The basic relation in set theory is that of elementhood, or membership. We write \ (a\in A\) to indicate that the object \ (a\) is an element, or a member, of ...

WebSep 5, 2024 · Theorem 1.1.1. Two sets A and B are equal if and only if A ⊂ B and B ⊂ A. If A ⊂ B and A does not equal B, we say that A is a proper subset of B, and write A ⊊ B. The set θ = {x: x ≠ x} is called the empty set. This set clearly has no elements. Using Theorem 1.1.1, it is easy to show that all sets with no elements are equal. WebDec 14, 2015 · 6. Two sets are equal if and only if they share the same elements. Thus there is no distinction between the sets { { a }, { b } } and { { b }, { a } }.
