摘要

让（X=Sp(1,n)/Sp(n)\）是具有左不变哈量的四元双曲空间，对标量是唯一的，其中 n 大于或等于 1，X 的 Fürstenberg 边界表示为（\Sigma \）。在本文中，我们将重点研究与 \(\Sigma\) 上的矢量值 \(L^2\)-space 的泊松变换相关的 X 上的 Plancherel 公式。通过傅里叶-雅可比变换和傅里叶-泊松变换，我们得出了 Sp(1, n) 在 \(L^2(X)\) 上的单元表示的 Plancherel 分解。

Fourier-Poisson Transforms Associated with the Principal Series Representations of Sp(1, n)

Let \(X=Sp(1,n)/Sp(n)\) be the quaternion hyperbolic space with a left invariant Haar measure, unique up to scalars, where n is greater than or equal to 1. The Fürstenberg boundary of X is denoted as \(\Sigma \). In this paper, we focus on the Plancherel formula on X associated with the Poisson transform of vector-valued \(L^2\)-space on \(\Sigma \). Through the Fourier-Jacobi transform and the Fourier-Poisson transform, we derive the Plancherel decomposition of the unitary representation of Sp(1, n) on \(L^2(X)\).
