For any binary relation ▷ on a set X, define the binary relation by letting xy we do not have ▷y. Let be a binary relation on a set X, and define binary relations ~ letting I~y ⇒ï≥y and yx, and and by I>Y ⇒ Iy and yr. (a) Argue that, if relation is complete and transitive, then the relation~~ is reflexive (rr), transitive (~y and y~ z implies that ~ z), and symmetric (ry implies that yr). [Said differently, you're showing is an equivalence relation.] 2 (b)Argue that, if relation is complete and transitive, then the relation is asymmetric (ry implies that yr) and negative transitive (ry and y z implies that rz).
