Abstract: | In this paper we consider the Dunkl operators T
j
, j = 1, . . . , d, on and the harmonic analysis associated with these operators. We define a continuous Dunkl Gabor transform, involving the Dunkl
translation operator, by proceeding as mentioned in 20] by C.Wojciech and G. Gigante. We prove a Plancherel formula, an inversion formula and a weak uncertainty principle for it. Then, we show that the portion of the continuous Dunkl Gabor transform
lying outside some set of finite measure cannot be arbitrarily too small. Similarly, using the basic theory for the Dunkl
continuous wavelet transform introduced by K. Trimèche in 18], an analogous of this result for the Dunkl continuous wavelet
transform is given. Finally, an analogous of Heisenberg’s inequality for a continuous Dunkl Gabor transform (resp. Dunkl continuous
wavelet transform) is proved.
