Essential Whittaker functions for $\mathrm{GL}(n)$
Doc. Math., J. DMV 18, 1191-1214 (2013)
Summary
Summary: We give a constructive proof of the existence of the essential Whittaker function of a generic representation of $GL(n,F)$, for $F$ a non-archimedean local field, using mirabolic restriction techniques.
