Low regularity global well-posedness for the two-dimensional Zakharov system
Daoyuan Fang, Hartmut Pecher, Sijia Zhong
The two-dimensional Zakharov system is shown to have a unique global solution for data without finite energy if the L^2 - norm of the Schrödinger part is small enough. The proof us…

L^2-concentration phenomenon for Zakharov system below energy norm
Daoyuan Fang, Sijia Zhong
In this paper, we'll prove a L^2-concentration result of Zakharov system in space dimension two, with radial initial data (u_0,n_0,n_1)\in H^s\times L^2\times H^{-1} ({16/17}<s<1),…
