%0 Journal Article %T Riesz Transform on the Dual of the Laguerre Hypergroup %A Mohamed Nejib Lazhari %A Taieb Ahmed %J Journal of Mathematics Research %D 2012 %I %R 10.5539/jmr.v4n3p50 %X In this paper, we define the Riesz transform on the dual of the Laguerre hypergroup associated with Plancherel measure and we give some properties for this transform. Also we investigate $L^p$-boundedness of this operator and under this definition, the higher order Riesz transform is given. Moreover we establish that the Riesz transform can be extended as a principal value singular integral operator and it is a multiplier operator under the Fourier transform. %U http://www.ccsenet.org/journal/index.php/jmr/article/view/15513
