Theorem 1
Let $a=\pm 3r^2=\frac{x_2^2-3x_1x_3}{3x_3^2}$, $r>0$, and $t=-x_3$. Suppose Then, the solution $u$ to the Cauchy problem for E:KPII-intro with initial data $u_0$ satisfies : as $t\to +\infty$, Here, $s_c(\lambda)$ denotes the scattering data of $u_0$, $a$ characterizes the stationary points in the phase, and $t$ corresponds to the direction of KPII propagation.
