相对超尖点表示是相对朗兰兹纲领中的超尖点表示的类似物。本工作研究相对超尖点表示使用顶级程度外群通过施奈德-Stuhler对偶。作为例子,确定了Flicker-Rallis情形和对角情形的相对超尖点谱。
Relatively supercuspidal representations are analogue of supercuspidal representations in the relative Langlands program. This work studies relatively supercuspidal representations using top degree Ext-groups via the Schneider-Stuhler duality. As examples, the relatively supercuspidal spectra for the Flicker-Rallis case and the diagonal case are determined.
