Abstract

We prove explicit L-p bounds for second order Riesz transforms of the sub-Laplacian and of the Laplacian in the Lie groups H, SU(2), and (SL) over tilde (2). Our proof makes use of martingale transform techniques and specific commutation properties between the complex gradient and the sub-Laplacian in those Lie groups.
