Averages of simplex Hilbert transforms

Abstract

We study a multilinear singular integral obtained by taking averages of simplex Hilbert transforms. This multilinear form is also closely related to Calderón commutators and the twisted paraproduct. We prove L^p bounds in dimensions two and three and give a conditional result valid in all dimensions.
