有限Coxeter群的Segal-Bargmann分析及其热核

On Segal-Bargmann analysis for finite Coxeter groups and its heat kernel

Stephen Bruce Sontz

摘要:

我们证明了涉及三个版本的积分核的恒等式(这里介绍两个)的Segal-Bargmann变换与有限Coxeter群作用在有限维,真正的欧几里得空间(第一个版本基本上是在同一时间由Ben Saïd和Elrsted以及Soltani独立提出的)和Dunkl热核,由于Rösler,与同一Coxeter群相关的Dunkl Laplacian。除了一个关系外,我们的所有关系最初都是由于霍尔在欧几里得空间的标准西格尔-巴格曼分析的背景下提出的。Hall的结果(平凡Dunkl结构和任意有限维)以及我们自己在$μ$ -变形量子力学中的结果(非平凡Dunkl结构,一维)是这里证明的结果的特例。所以我们可以把所有这些与Coxeter群相关的Segal-Bargmann变换理解为Hall型变换。特别是,我们定义了一个类似的霍尔的版本C广义Segal-Bargmann变换,然后示出的Dunkl卷积与Dunkl热核随后解析延续。在版本C的上下文中,我们还介绍了一个新的Segal-Bargmann空间和一个新的变换相关的Dunkl理论。此外,我们在A版和C版的Segal-Bargmann核之间似乎有一种新的关系。

英文摘要:

We prove identities involving the integral kernels of three versions (two being introduced here) of the Segal-Bargmann transform associated to a finite Coxeter group acting on a finite dimensional, real Euclidean space (the first version essentially having been introduced around the same time by Ben Saïd and Ørsted and independently by Soltani) and the Dunkl heat kernel, due to Rösler, of the Dunkl Laplacian associated with the same Coxeter group. All but one of our relations are originally due to Hall in the context of standard Segal-Bargmann analysis on Euclidean space. Hall's results (trivial Dunkl structure and arbitrary finite dimension) as well as our own results in $μ$-deformed quantum mechanics (non-trivial Dunkl structure, dimension one) are particular cases of the results proved here. So we can understand all of these versions of the Segal-Bargmann transform associated to a Coxeter group as Hall type transforms. In particular, we define an analogue of Hall's Version C generalized Segal-Bargmann transform which is then shown to be Dunkl convolution with the Dunkl heat kernel followed by analytic continuation. In the context of Version C we also introduce a new Segal-Bargmann space and a new transform associated to the Dunkl theory. Also we have what appears to be a new relation in this context between the Segal-Bargmann kernels for Versions A and C.
