comment How does the right regular of GL(n, R) and GL(n,Qp) decompose?
Thanks for also answering my consecutive answer. I have to diggest the information, you gave, but that seems to describe the situation pretty thorough.

Thanks for this answer. Lot of material here to be checked. But you don't know anything compromised as one can find e.g. in Gelbart-Jacquet for the global picture $L^2( GL(2, k) \backslash GL(2, \mathbb{A})=$ cuspidal rep. + characters + direct integrals involving parabolic induction?

Following your suggestion, I edited the title.

comment What is the relationship amongst all the different kinds of spectra?
The spectrum of a unital commutative $C^*$ algebra $A$ is defined such that $Hom_{top}(Spec(A), \mathbb{C}) = A$, the same holds for the spectra in homotopy theory with different hom. So I always understand this as a question about representable functors. Does this make sense?

comment generalisation of GL(3,R) polar decomposition
@Carnahan: It is sometimes called polar decomposition, since $PSL_2(\mathbb{R}) / PSO(2)$ is the upper halfplane $H$, and the above decompositions give you the elements of $H$ in polar coordinates, but you are right in general.
