Reflexive Relations and Examples

Let A be a set. A relation R on A is a subset of A x A. Let R be a relation on A. We say R is reflexive of aRa for all a in A. In this video we go over this definition more carefully and we do several examples where we determine if the relation is reflexive. I hope this helps someone who i

Equivalence Relations - Reflexive, Symmetric, and Transitive

A relation that is all three of reflexive, symmetric, and transitive, is called an equivalence relation. Reflexive means that every element relates to itself. Symmetry means that if one element relates to another, the same is true in the reverse. Transitive means that if a relates to b, an

Reflexive, Symmetric, and Transitive Relations on a Set

A relation from a set A to itself can be though of as a directed graph. We look at three types of such relations: reflexive, symmetric, and transitive. A relation is reflexive if every element relates to itself, that is has a little look from itself to itself. A relation is symmetric if

BM7. Binary Relations

Note: as noted below, 'equals' is an anti-symmetric relation. But, in practice, intuition for partially ordered sets starts with "less than or equals." Basic Methods: We define the Cartesian product of two sets X and Y and use this to define binary relations on X. We explain the propert

Prove that R is an Equivalence Relation on Z: xRy if x + 3y is even

In this video we define a relation R on the set of integers Z as follows: We say x R y if x + 3y is even. We prove that R is an equivalence relation on Z. To do this we show that R is reflexive, symmetric, and transitive. The pencils I used in this video: https://amzn.to/3bCpvpt The pape
