Metric Spaces 1. Equivalence Relations Definition 1.1. A relation on a set S is a subset R ⊆ S × S. If (a, b) ∈ R, we write a ∼R b (or just a ∼ b). Example 1.2. (1) Let S be the set of members of our class, and let (a, b) ∈ R if person a is shorter than person b. (2) Let S = Z and R = {(a, b) ∈ Z | b = 2a}. Thus, 4 ∼ 8 and 8 ∼ 16. Definition 1.3. A relation ∼ on a set S is an equivalence relation if for all a, b, c ∈ S, (1) a ∼ a (reflexivity) (2) a ∼ b =⇒ b ...
