condor.depaul.eduEquivalence Relations • A relation on a set that satisfies the three properties of reflexivity, symmetry, and transitivity is called an equivalence ... R is symmetric because whenever (x,y) is in R, (y,x) is in R as well. R is transitive because whenever (x,y) and (y,z) are in R, (x,z) is in R as well. Consider the relation R on a set {1,2,3 ...

www.eecs.umich.eduwe know that ad = bc, and cf = de, multiplying these two equations we get adcf = bcde => af = be => ((a, b), (e, f)) ∈ R Hence it is transitive. Thus R is an equivalence relation. 14) Determine whether the relations represented by the following zero-one matrices are equivalence relations. 4 points a) 1 1 1 0 1 1 1 1 1

www-math.ucdenver.eduthe equivalence classes of R form a partition of the set S. More interesting is the fact that the converse of this statement is true. Theorem 3.6: Let F be any partition of the set S. Define a relation on S by x R y iff there is a set in F which contains both x and y. Then R is an equivalence relation and the equivalence classes of R are the ...
