$\mathcal{U}_q(\mathfrak{g}_\mathbb{R})$的抛物正表示

Parabolic Positive Representations of $\mathcal{U}_q(\mathfrak{g}_\mathbb{R})$

Ivan Chi-Ho Ip

摘要:

通过量子化对应于任意抛物子群的经典抛物归纳法,构造了$\mathcal{U}_q(\mathfrak{g}_\mathbb{R})$及其模偶的一族新的不可约表示,使得$\mathcal{U}_q(\mathfrak{g}_\mathbb{R})$的生成元作用于希尔伯特空间上的正自伴算子。这推广了建立良好的正表示,对应于诱导的最小抛物(即博雷尔)子群。我们还详细研究了$A_n$型作用于具有最小函数维数的$L^2(\mathbb{R}^n)$的特殊情形,建立了它的中心特征标和泛$\mathcal{R}$算子的性质.我们构建了一个积极的版本的仿射量子群$\mathcal{U}_q(\widehat{\mathfrak{sl}}_{n+1})$的评估模块建模在这个最小的正表示类型$A_n$。

英文摘要:

We construct a new family of irreducible representations of $\mathcal{U}_q(\mathfrak{g}_\mathbb{R})$ and its modular double by quantizing the classical parabolic induction corresponding to arbitrary parabolic subgroups, such that the generators of $\mathcal{U}_q(\mathfrak{g}_\mathbb{R})$ act by positive self-adjoint operators on a Hilbert space. This generalizes the well-established positive representations which corresponds to induction by the minimal parabolic (i.e. Borel) subgroup. We also study in detail the special case of type $A_n$ acting on $L^2(\mathbb{R}^n)$ with minimal functional dimension, and establish the properties of its central characters and universal $\mathcal{R}$ operator. We construct a positive version of the evaluation module of the affine quantum group $\mathcal{U}_q(\widehat{\mathfrak{sl}}_{n+1})$ modeled over this minimal positive representation of type $A_n$.
