  • Muscalu, Tao, and Thiele prove Lp estimates for the "Biest"operator defined on Schwartz functions by the map C via a time-frequency argument that produces bounds for all multipliers with non-degenerate trilinear simplex symbols. In this article we prove Lp estimates for a pair of simplex multipliers defined on Schwartz functions by the maps
