Abstract

We relate the analytic conductor of a generic irreducible representation of GLn(R)\mathrm{GL}_n(\mathbb{R}) to the invariance properties of vectors in that representation. The relationship is an analytic archimedean analogue of some aspects of the classical non-archimedean newvector theory of Casselman and Jacquet--Piatetski-Shapiro--Shalika. We illustrate how this relationship may be applied in trace formulas to majorize sums over automorphic forms on PGLn(Z)\PGLn(R)\mathrm{PGL}_n(\mathbb{Z}) \backslash \mathrm{PGL}_n(\mathbb{R}) ordered by analytic conductor.
