Query: The ideal structure of the Hecke C*-algebra of Bost and Connes   We compute explicitly the primitive ideal space of the Bost-Connes Hecke
C*-algebra by embedding it as a full corner in a transformation group
C*-algebra and applying a general theorem of Williams. This requires the
computation of the quasi-orbit space for the action of the multiplicative
positive rationals on the space of finite adeles. We then carry out a similar
computation for the action of the nonzero rationals on the space of full
adeles.
