In this paper, we consider the modified Ostrovsky, Stepanyams and Tsimring equation . We prove that the associated initial value problem is locally well-posed in Sobolev spaces for . We also prove that our result is sharp in the sense that the flow map of this equation fails to be in for . Moreover, we prove that for any and , its solution converges in to that of the mKdV equation if tends to 0.

在本文中,我们考虑了修正的Ostrovsky,Stepanyams和Tsimring方程 。我们证明了相关的初值问题在Sobolev空间中是局部适定的 对于 。我们还证明了我们的结果是精确的,因为该方程的流程图无法 在 对于 。而且,我们证明对于任何 和 ,其解决方案收敛于 如果mKdV方程 趋于0。
