WebThe cardinality of the collection of Lebesgue measurable sets is 2c. Proof By Lemma 2.16, since K 2 L and „(K) = 0 any subset A µ K satisfies A 2 L. The number of subsets of K is 2c hence the cardinality of L is ‚ 2c. But every Lebesgue measurable set is a subset of R, of which there are 2c. Hence we get the result. ¥ 6 WebFor each set A, there exists a set B whose members are subsets of A. We call B the power set of A and write B = P(A). Note that P(∅) is the singleton {∅}. §2.
