Abstract

For p>p0=2λ2λ+1p>p_0=\frac{2\lambda}{2\lambda+1} with λ>0\lambda>0, the Hardy space Hλp(R+2)H_{\lambda}^p(\mathbb{R}_+^2) associated with the Dunkl transform Fλ\mathcal{F}_\lambda and the Dunkl operator DD on the real line R\mathbb{R}, where Dxf(x)=f(x)+λx[f(x)f(x)]D_xf(x)=f'(x)+\frac{\lambda}{x}[f(x)-f(-x)], is the set of functions F=u+ivF=u+iv on the upper half plane R+2={(x,y):xR,y>0}\mathbb{R}^2_+=\left\{(x, y): x\in\mathbb{R}, y>0\right\}, satisfying λ\lambda-Cauchy-Riemann equations: Dxuyv=0 D_xu-\partial_y v=0, yu+Dxv=0\partial_y u +D_xv=0, and supy>0RF(x+iy)px2λdx<\sup\limits_{y>0}\int_{\mathbb{R}}|F(x+iy)|^p|x|^{2\lambda}dx<\infty in [7]. Then it is proved in [11] that the real Dunkl-Hardy Spaces Hλp(R)H_{\lambda}^p(\mathbb{R}) for 11+γλ<p1\frac{1}{1+\gamma_\lambda}<p\leq1 are Homogeneous Hardy Spaces. In this paper, we will continue to investigate λ\lambda-Hilbert transform on the real Dunkl-Hardy Spaces Hλp(R)H_{\lambda}^p(\mathbb{R}) for 11+γλ<p1\frac{1}{1+\gamma_\lambda}<p\leq1 with γλ=1/(4λ+2)\gamma_\lambda=1/(4\lambda+2) and extend the results of λ\lambda-Hilbert transform in [7].
