... the procedure until all discs have been discarded. The sum of the areas of E1 , E2 , . . . must be at least 1 since we have discarded all discs. Since the area of an expanded disc is 9 times the area of the original disc, the sum Area(D1 ) + Area(D2 ) + · · · must be at least 1/9. Consider two disc ...

... particular element g ∈ G permutes the elements of G. We can work in a Galois extension of Q containing L, and each automorphism in the Galois group restricts to one of the σi on L. Thus P + N and P N belong to the fixed field of the Galois group, which is Q. 2. Since the xj are algebraic integers, so ...
