By Herbert Federer

From the stories: "... Federer's well timed and gorgeous booklet certainly fills the necessity for a entire treatise on geometric degree conception, and his distinctive exposition leads from the principles of the idea to the newest discoveries. ... the writer writes with a particular type that's either typical and powerfully reasonably-priced in treating a sophisticated topic. This e-book is a tremendous treatise in arithmetic and is key within the operating library of the fashionable analyst."

Zf 4 is a Borel regular measure over a complete, separable metric space X, 0 < &(A) < 00, and @({x}) =0 whenever x EA, then A has a I$ nonmeasurablesubset. Proof. We consider the class r of all closed subsets C of A for which 4 (C) > 0, hence card(C) = 2’O. Noting that card(r) I 2Ko, we wellorder r so that, for each CE~, the set rc of all predecessors of C has cardinal less than 2’0. By induction with respect to this wellordering we define functions f and g on r such that, for each CEr, f(C) and g(C) are distinct elements of c - Cfvc) u gml ; this is possible because card [ f(rc) u g (Q] = 2 card (&-) < 2’O = card (C) .

I@ #(Ail. (2) Zf 4(A)< CO,then A has a 4 hull. (3) Zf Au B is 4 measurableand $(A)+$(B)=~J(Au and B are 4 measurable. hence 4 (C n B) = 0,4 (C - A) = 0, A is 4 measurable. We deduce (4) from (3) with A= f -l(C), B= f -‘(Y- C). To prove (5) we assume that A is a 4L S measurable subset of S, choose 4 hulls S’ and A’ of S and A, with A’cS’, and compute B)< 00, then A (4) Zf$(X)< co,f: X-+ Yand C isanf, 4 measurableset,thenf-‘(C) is 4 measurable. hence B = A’- [(A’n S) - A] is 4 measurable and B n S= A.

To prove (5) we assume that A is a 4L S measurable subset of S, choose 4 hulls S’ and A’ of S and A, with A’cS’, and compute B)< 00, then A (4) Zf$(X)< co,f: X-+ Yand C isanf, 4 measurableset,thenf-‘(C) is 4 measurable. hence B = A’- [(A’n S) - A] is 4 measurable and B n S= A. Simple examples show that none of the above five propositions need to hold in case 4 is irregular. (1) and (2) fail when X is an infinite set, 4 (a) = 0,4 (A) = 1 for each finite A c X, 4 (A) = 2 for each infinite A F X. (3) and (4) fail when card(X) = 3, #(a) = 0, 4 (X) = 2, $(A) = 1 for every nonempty proper subset A of X.
