Question

100%

Let P be a set on which a binary relation < is defined such that,
for all r, y, z € P,
(a) * <x is false,
(b) x <y and y < z imply x < z.
Prove that if < is defined by
r <y+ (* <y or x = y),
%3D
then < is an order on P, and moreover every order on P arises from
a relation < satisfying (a) and (b). (A binary relation satisfying
(a) and (b) is called a strict order.)
