本文从概念上描述了Cai-Friedberg-Ginzburg-Kaplan的扭曲二重积分。这也将构造扩展到四元酉群。我们在本文中统一进行展开论证。要做到这一点,我们定义了一个家庭的退化惠特克系数,适合在这个设置和研究他们的一些属性。我们还证明了某些相关的全球和当地的结果,使用相同的工具。
We describe the twisted doubling integrals of Cai–Friedberg–Ginzburg–Kaplan in a conceptual way. This also extends the construction to the quaternionic unitary groups. We carry out the unfolding argument uniformly in this article. To do so, we define a family of degenerate Whittaker coefficients that are suitable in this setup and study some of their properties. We also prove certain related global and local results that use the same tools.
