*“Dunkl theory and Hörmander multiplier theoremin the rational Dunkl


Dunkl theory is a generalization of Fourier analysis and special function
theory related to root systems and reflections groups. The Dunkl operators
are deformations of the directional derivatives related to the reflection
group. We shall discuss the objects related to the Dunkl Laplacian. In the
one-dimensional and in the product case the heat kernel can be expressed
explicitly in terms of classical special functions. In the general case
considered in this talk, no such precise information is available.
Furthermore, we will discuss an analogue of the classical Hörmander
multiplier theorem in the rational Dunkl setting.

This talk is based on joint work with Jacek Dziubanski.

Tutti gli interessati sono invitati a partecipare.
