摘要

周期 KP-I 初值问题 tu+x3ux1y2u+x(u2/2)=0\partial_t u+\partial_x^3 u-\partial_x^{-1}\partial_y^2 u+\partial_x (u^2/2)=0 定义在 Tx,y2×RtT_{x,y}^2\times R_t 上,初始条件为 u(0)=ϕu(0)=\phi。该问题在能量空间 E1=E1(T2)={ϕ:T2R:ϕ^(0,n)=0, nZ{0}}E^1 = E^1 (T^2)=\{\phi: T^2\to R:\hat\phi(0,n)=0,\ \forall n\in Z \setminus \{0\}\}ϕE1(T2)=ϕ^(m,n)(1+m+n/m)l2(Z2)<||\phi||_{E^1 (T^2)}=||\hat{\phi}(m,n)(1+|m|+|n/m|)||_{l^2(Z^2)}<\infty 中是全局适定的。
