On classical doubling method gamma factors for certain depth zero representations
Johannes Girsch, Elad Zelingher
Piatetski-Shapiro--Rallis discovered an integral representation construction, known as the doubling method, for the tensor product -function of a cuspidal automorphic representa…

On families of degenerate representations of GL_n(F)
Johannes Girsch, David Helm
We consider the stratification of the category of smooth representations of $\mbox{GL}_n(F)$ (for a -adic field) induced by degenerate Whittaker models. We show that, remark…

Newforms in Cuspidal Representations
Johannes Girsch, Robert Kurinczuk
We consider newform vectors in cuspidal representations of -adic general linear groups. We extend the theory from the complex setting to include~-modular representations w…
