我们建立了$mathrm{GL}_n(F)的一个显式Plancherel分解其中E/F是利用Asai γ-因子的局部函数方程对特征为零的局部域的二次扩张。我们还给出了这个Plancherel公式的两个应用:第一,通过完成局部相对特征之间的比较,这是由W。其次,在酉群的情形下,证明了关于形式度的Hiraga-Ichino-Ikeda猜想。
We establish an explicit Plancherel decomposition for $mathrm{GL}_n(F)ackslash mathrm{GL}_n(E)$ where $E/F$ is a quadratic extension of local fields of characteristic zero by making use of a local functional equation for Asai $gamma$-factors. We also give two applications of this Plancherel formula: first to the global Ichino-Ikeda conjecture for unitary groups by completing a comparison between local relative characters that was left open by W. Zhang and secondly to the Hiraga-Ichino-Ikeda conjecture on formal degrees in the case of unitary groups.
