Global solutions for 1D cubic defocusing dispersive equations, Part V: low regularity NLS

Mihaela Ifrim, Ryan Martinez, Daniel Tataru

This article is motivated by a broad conjecture, formulated by the first and last authors in earlier work, asserting that one-dimensional cubic defocusing dispersive flows with sma…

Wave packet decompositions and sharp bilinear estimates for rough Hamiltonian flows

Robert Schippa, Daniel Tataru

The goal of this paper is to prove bilinear estimates for rough dispersive evolutions satisfying non-degeneracy and transversality assumptions. The estimates generalize the s…

Enhanced lifespan bounds for 1D quasilinear Klein-Gordon flows

Hongjing Huang, Mihaela Ifrim, Daniel Tataru

In this article we consider one-dimensional scalar quasilinear Klein--Gordon equations with general nonlinearities, on both and . By employing a refined mo…

Local well-posedness of the skew mean curvature flow for large data

Jiaxi Huang, Daniel Tataru

The skew mean curvature flow is an evolution equation for dimensional ma\-nifolds embedded in (or more generally, in a Riemannian manifold). It can be viewed…

Large data global well-posedness for the modified Novikov-Veselov system

Adrian Nachman, Peter Perry, Daniel Tataru

The modified Novikov-Veselov system (mNV) is a cubic third order dispersive evolution in two space dimensions. It is also completely integrable, belonging to the same hierarchy as…

Global solutions for cubic quasilinear ultrahyperbolic Schrödinger flows

Mihaela Ifrim, Ben Pineau, Daniel Tataru

In recent work, two of the authors proposed a broad global well-posedness conjecture for cubic quasilinear dispersive equations in two space dimensions, which asserts that global w…
