摘要

本文考虑与Ostrovsky方程相关的初值问题(IVP)ut+x3u±x1u+uxu=0,xR,  tR,u(x,0)=u0(x).}\left. \begin{array}{rl} u_t+\partial_x^3 u\pm \partial_x^{-1}u +u \partial_x u &\hspace{-2mm}=0,\qquad\qquad x\in\mathbb R,\; t\in\mathbb R,\\ u(x,0)&\hspace{-2mm}=u_0(x). \end{array} \right\} 我们研究了该IVP在加权Sobolev空间 Zs,s2:={uHs(R):DxsuL2(R)}L2(xsdx),Z_{s,\frac{s}2}:=\{u\in H^s(\mathbb R):D_x^{-s} u\in L^2(\mathbb R)\}\cap L^2(|x|^s dx ), 中当 34<s1\frac34<s\leq 1 时的适定性。
