The full range of uniform bounds for the bilinear Hilbert transform
Gennady Uraltsev, Michał Warchalski
We prove uniform uniform bounds for the family of bilinear Hilbert transforms $\mathrm{BHT}_β [f_1, f_2] (x) := \mathrm{p.v.} \int_{\mathbb{R}} f_1 (x - t) f_2 (x + βt) \fr…

Almost sure local well-posedness for cubic nonlinear Schrodinger equation with higher order operators
Jean-Baptiste Casteras, Juraj Foldes, Gennady Uraltsev
In this paper, we study the local well-posedness of the cubic Schrödinger equation: \[ (i \partial_t - \mathscr{L}) u = \pm |u|^2 u \quad \text{ on } I \times \mathbb{R}^d, \] with…
