Journal ArticleDOI
Global Schrödinger maps in dimensions $d≥ 2$: Small data in the critical Sobolev spaces
TL;DR: In this article, it was shown that the Schrodinger map initial-value problem admits a unique global smooth solution 2 C(R : H 1 Q ), Q 2 S 2, provided that the data H1 Q is smooth and satises the smallness condition.
Journal ArticleDOI
On the 2d Zakharov system with L^2 Schr\"odinger data
TL;DR: In this article, the authors prove local in time well-posedness for the Zakharov system in two space dimensions with large initial data in L^2 x H −1/2 + H −3/2.
Journal ArticleDOI
Convolutions of singular measures and applications to the Zakharov system
Ioan Bejenaru,Sebastian Herr +1 more
TL;DR: In this article, a uniform L 2 -estimation for the convolution of singular measures with respect to transversal submanifolds is proved in arbitrary space dimension, and the results of Bennett-Bez are used to extend previous work of Bejenaru-Herr-Tataru.
Journal ArticleDOI
On the 2D Zakharov system with L2 Schrödinger data
TL;DR: In this paper, the authors prove local in time well-posedness for the Zakharov system in two space dimensions with large initial data in L 2 × H−1/2 × H −3/2.
Journal ArticleDOI
The Cubic Dirac Equation: Small Initial Data in H-1/2 (R-2)
Ioan Bejenaru,Sebastian Herr +1 more
TL;DR: In this paper, the authors established global well-posedness and scattering for the cubic Dirac equation with small initial data in the critical space (H^{\frac{1}{2}}} (\mathbb{R}^{2}} ) is established.
