紧Heckman-Opdam环境下的热半群与Segal-Bargmann变换

The heat semigroup in the compact Heckman-Opdam setting and the Segal-Bargmann transform

Heiko Remling, Margit Rösler

摘要:

本文的第一部分研究了紧Weyl群不变条件下的热方程和Heckman-Opdam Laplacian算子的热核。特别地,该拉普拉斯算子在仿射外尔群的基本凹穴上产生Feller-马尔可夫半群。本文的第二部分致力于Segal-Bargmann变换在我们的上下文中。定义了一个全纯函数的希尔伯特空间,使得$L^2$ -热变换成为酉同构.

英文摘要:

In the first part of this paper, we study the heat equation and the heat kernel associated with the Heckman-Opdam Laplacian in the compact, Weyl-group invariant setting. In particular, this Laplacian gives rise to a Feller-Markov semigroup on a fundamental alcove of the affine Weyl group. The second part of the paper is devoted to the Segal-Bargmann transform in our context. A Hilbert space of holomorphic functions is defined such that the $L^2$-heat transform becomes a unitary isomorphism.
