Transcribed Image Text:12.3. Consider the formula
³x³y³z (P(x, y) P(z,y) ^ P(x, z) ^ ¬P(z, x)).
Under each of these interpretations, is this formula true? In each case, R is the
relation corresponding to P.
(a) U=N, R= {(x, y) : x < y}.
(b) U=N, R={(x,x+ 1) :x ≥ 0}.
(c) U= the set of all bit strings, R = {(x, y) : x is lexicographically earlier
than y}.
(d) U= the set of all bit strings, R = {(x, y): y=x0 or y=x1}.
(e) U=P(N), R={(A, B) : ACB}.
