Equivalence Relation: How to Prove an Equivalence Relation

Web1st step. The theorem states that if ~ is an equivalence relation on a nonempty set A, then A/~ forms a partition of A. In order to prove this theorem, we need to show that: Every element of A belongs to exactly one element of A/∼. The elements of A/∼ are nonempty. The elements of A/∼ are pairwise disjoint.

Webb) Define e 1 ≡ e 2 iff e 1 and e 2 are in same simple cycle. If ≡ is equivalence relation on set of every edge which is not bridge, it proves original claim. (∵ Equivalence class forms partition of set.) If e is not a bridge, e is in some simple cycle. It means e ≡ e. It’s trivial that e 1 ≡ e 2 implies e 2 ≡ e 1.

WebAlso, given R is equivalence relation, Now, let R − 1 = {(b, a) ∣ (a, b) ∈ R} We will check whether R − 1 is reflexive, symmetric, transitive or an equivalence relation. Reflexive: Since, R is reflexive ⇒ (a, a) ∈ R ⇒ (a, a) ∈ R − 1 (by def of R − 1) Hence, R − 1 is reflexive. Symmetric: Let (b, a) ∈ R − 1 ⇒ (a, b ...
