Title: A triangular Hilbert transform with curvature, I & II.


Abstract: The triangular Hilbert is a two-dimensional bilinear singular
originating in time-frequency analysis. No Lp bounds are currently
known for this operator.
In these two talks we discuss a recent joint work with Michael Christ
on a variant of the triangular Hilbert transform involving curvature.
This object is closely related to the bilinear Hilbert transform with
curvature and a maximally modulated singular integral of Stein-Wainger
type. As an application we also discuss a quantitative nonlinear Roth
type theorem on patterns in the Euclidean plane.
The second talk will focus on the proof of a key ingredient, a certain
regularity estimate for a local operator.
