L2 and Hp boundedness of strongly singular operators and oscillating operators on Heisenberg groups

Woocheol Choi

In the first part, we obtain sharp results for L^2 boundedness of strongly singular operators on the Heisenberg group. We also define the oscillating convolution operators on the H…

Oscillating convolution operators on the Heisenberg group

Woocheol Choi

In this paper, we consider oscillating convolution operotors on the Heisenberg group $H_{a}^{n}$ with respect to the norm $ρ (x, t) = ρ_{1} (b x, b t)$ with $ρ_{1} (x, t) = (∣ x ∣^{4} + t^{2})^{1/4}$ .…
