  Automorphic representations can be studied in terms of the embeddings of
abstract models of representations into spaces of functions on Lie groups that
are invariant under discrete subgroups. In this paper we describe an adelic
framework to describe them for the group GL(n,R), and provide a detailed
analysis of the automorphic distributions associated to the mirabolic
Eisenstein series. We give an explicit functional equation for some
distributional pairings involving this mirabolic Eisenstein distribution, and
the action of intertwining operators.
