We prove Strichartz estimates with fractional loss of derivatives for the Schrödinger equation on any Riemannian compact manifold. As a consequence we infer low regularity local wellposedness results in any dimension, as well as global existence results for the Cauchy problem of nonlinear Schrödinger equations on surfaces in the case of defocusing polynomial nonlinearities, and on threemanifolds in the case of cubic defocusing nonlinearities. We also discuss the optimality of these Strichartz estimates on spheres.

The cubic nonlinear Schrödinger equation in two dimensions with radial data

"... We establish global wellposedness and scattering for solutions to the masscritical nonlinear Schrödinger equation iut + ∆u = ±u  2 u for large spherically symmetric L 2 x(R 2) initial data; in the focusing case we require, of course, that the mass is strictly less than that of the ground state ..."

We establish global wellposedness and scattering for solutions to the masscritical nonlinear Schrödinger equation iut + ∆u = ±u  2 u for large spherically symmetric L 2 x(R 2) initial data; in the focusing case we require, of course, that the mass is strictly less than that of the ground state. As a consequence, we deduce that in the focusing case, any spherically symmetric blowup solution must concentrate at least the mass of the ground state at the blowup time. We also establish some partial results towards the analogous claims in other dimensions and without the assumption of spherical symmetry.

"... We show that wave maps from Minkowski space R 1+n to a sphere S m−1 are globally smooth if the initial data is smooth and has small norm in the critical Sobolev space ˙ H n/2, in all dimensions n ≥ 2.

We show that wave maps from Minkowski space R 1+n to a sphere S m−1 are globally smooth if the initial data is smooth and has small norm in the critical Sobolev space ˙ H n/2, in all dimensions n ≥ 2. This generalizes the results in the prequel [37] of this paper, which addressed the highdimensional case n ≥ 5. In particular, in two dimensions we have global regularity whenever the energy is small, and global regularity for large data is thus reduced to demonstrating nonconcentration of energy.
Global wellposedness of the BenjaminOno equation in H¹(R)

"... We show that the BenjaminOno equation is globally wellposed in H s (R) for s ≥ 1. This is despite the presence of the derivative in the nonlinearity, which causes the solution map to not be uniformly continuous in H s for any s [15]. The main new ingredient is to perform a global gauge transforma ..."

We show that the BenjaminOno equation is globally wellposed in H s (R) for s ≥ 1. This is despite the presence of the derivative in the nonlinearity, which causes the solution map to not be uniformly continuous in H s for any s [15]. The main new ingredient is to perform a global gauge transformation which almost entirely eliminates this derivative.

We obtain global wellposedness, scattering, uniform regularity, and global L6 t,x spacetime bounds for energyspace solutions to the defocusing energycritical nonlinear Schrödinger equation in R×R 4. Our arguments closely follow those in [11], though our derivation of the frequencylocalized interaction Morawetz estimate is somewhat simpler. As a consequence, our method yields a better bound on the L6 t,xnorm
