报告摘要：In the Heisenberg group of dimension 2n+1, we consider the sub-Laplacian with a drift in the horizontal coordinates. There is a related measure for which this operator is symmetric. The corresponding Riesz transforms are known to be $L^p$ bounded with respect to this measure. We prove that the Riesz transforms of order 1 are also of weak type $(1,1)$. This is based on joint work with P. Sj\"ogren.
