Genuine pro- Iwahori--Hecke algebras, Gelfand--Graev representations, and some applications
Fan Gao, Nadya Gurevich, Edmund Karasiewicz
We study the Iwahori-component of the Gelfand-Graev representation of a central cover of a split linear reductive group and utilize our results for three applications. In fact, it…
The Twisted Satake Transform and the Casselman-Shalika Formula for Quasi-Split Groups
Nadya Gurevich, Edmund Karasiewicz
We prove the Casselman-Shalika formula for unramified groups over a non-archimedean local field by studying the action of the spherical Hecke algebra on the space of compact spheri…
Poles of the Standard -function of and the Rallis-Schiffmann Lift
Nadya Gurevich, Avner Segal
We characterize the cuspidal representations of whose standard -function admits a pole at as the image of Rallis-Schiffmann lift for the commuting pair $\l…
Rankin-Selberg integral with Non-unique model for the standard L-function of
Nadya Gurevich, Avner Segal
Let L^S(π,s,st) be a partial L-function of degree 7 of a cuspidal automorphic representation πof the exceptional group G_2. Here we construct a Rankin-Selberg integral for represen…
