How to prove or where to find the radii of Starlikeness and Convexity of functions in Dunkl and q-Dunkl setting and what are the difficulties to meet in this subject?
Here you can find it for q-Bessel and for Bessel setting in references therein:
Article Radii of starlikeness and convexity of some q-Bessel functions
Thus, in principle, the rank one case of the Dunkl settings should (I would guess) follow from minor adaptations. For higher rank I have no idea of what can be done.
Using the convolution of harmonic functions, we introduce a generalization for a previously defined class of right half-strip harmonic mappings and determine sharp radii of univalence, full convexity and starlikeness for such functions
