WebDefinition 1. Two sets A and B (finite or infinite) are equivalent if there is a function f : A→ B such that • f is one-to-one; • f is onto; Note that if we want to show that A and B are not equivalent, we have to prove that no such function exists.

WebA relation on a set A is an equivalence relation if it is reflexive, symmetric, and transitive. We often use the tilde notation a ∼ b to denote a relation. Also, when we specify just one set, such as a ∼ b is a relation on set B, that means the domain & codomain are both set B. WebThe relation "is equivalent to " is reflexive, symmetric (implies ), and transitive and thus defines an equivalence relation on the set of all norms on . The norms p {\displaystyle p} and q {\displaystyle q} are equivalent if and only if they induce the same topology on X . {\displaystyle X.} [9] Any two norms on a finite-dimensional space are ...
