Oscillating convolution operators on the Heisenberg group
Abstract
In this paper, we consider oscillating convolution operotors on the Heisenberg group $H^n_a$ with respect to the norm $ρ(x,t) = ρ_1(b x, b t)$ with $ρ_1(x,t)= (|x|^4 + t^2)^{1/4}$. We obtain $L^2$ boundedness properties using the oscillatory integral estimates for degenerate phases in the Euclidean setting. Our result contains an improvement of the Lyall's result for the cases $\frac{a^2}{b^2} \geq C_β$.
