Given a well-ordered integral domain with unity e ED and positive elements D, and the mapping 0: Z→ D defined by 0(n)=ne Vn e Z. (a) Prove that e is the least positive element in D. (b) True or false? Justify your answer: The image set 0(Z) is a subring of D. (c) True or false? Justify your answer: If an element de D is not in 0(Z), then -d0(Z). :D\0(Z). Prove that SP, the set of (d) Suppose that the subset S CD is defined as S := positive elements of S. has no least element. What does this say about S? (e) Hence show that Z~ D, i.e., that any well-ordered integral domain is isomorphic to the ring of integers.
