A型根系广义球函数的Laplace型表示

A Laplace-type representation of the generalized spherical functions associated to the root systems of type A

Patrice Sawyer

摘要:

在本文中,我们推广了广义球函数的迭代表达式与$A$型根系以前获得的超出正规元素。在平面情况下,我们也给出了相应的表达式。从那里,我们得到了一个拉普拉斯型表示的广义球函数的根系类型$A$在Dunkl设置以及三角Dunkl设置。这种表示使我们能够精确地描述广义Abel变换的支持。由于Rejeb最近的结果,这使我们能够支持Dunkl交织算子。

英文摘要:

In this paper, we extend the iterative expression for the generalized spherical functions associated to the root systems of type $A$ previously obtained beyond regular elements. We also provide the corresponding expression in the flat case. From there, we derive a Laplace-type representation for the generalized spherical functions associated to the root systems of type $A$ in the Dunkl setting as well as in the trigonometric Dunkl setting. This representation leads us to describe precisely the support of the generalized Abel transform. Thanks to a recent result of Rejeb, this allows us to give the support for the Dunkl intertwining operator.
