Trilinear smoothing inequalities and a variant of the triangular Hilbert transform
Michael Christ, Polona Durcik, Joris Roos
Lebesgue space inequalities are proved for a variant of the triangular Hilbert transform involving curvature. The analysis relies on a crucial trilinear smoothing inequality develo…
