In this paper, we study solitary wave solutions of the Cauchy problem for Half-wave-Schrödinger equation in the plane. First, we show the existence and the orbital stability of the ground states. Second, we prove that given any speed v , traveling wave solutions exist and converge to the zero wave as the velocity tends to 1 . Finally, we solve the Cauchy problem for initial data in L x 2 H y s ( ℝ 2 ) , with s > 1 2 . The critical case s = 1 2 still stands as an interesting open problem.

半波薛定谔方程的孤立波和柯西问题的备注
在本文中,我们研究了平面上半波薛定谔方程的柯西问题的孤波解。首先,我们展示了基态的存在和轨道稳定性。其次,我们证明给定任何速度v , 行波解存在并且随着速度趋向于收敛到零波1 . 最后,我们解决了初始数据的柯西问题大号 X 2 H 是的 s ( ℝ 2 ) , 和s > 1 2 . 危急情况s = 1 2 仍然是一个有趣的开放问题。
