报告内容:We consider the Cauchy problem for the rotation-modified Kadomtsev-Petviashvili (RMKP) equation in the anisotropic Sobolev spaces. We prove that the Cauchy problem is locally well-posed which considerably improves the Theorem 1.4 of R. M. Chen, Y. Liu, P. Z. Zhang (Transactions of the American Mathematical Society, 364(2012), 3395--3425.). The key idea is that we divide the frequency space into regular region and singular region. We further prove that the Cauchy problem for RMKP equation is ill-posed in the sense that the flow map associated to the rotation-modified Kadomtsev-Petviashvili is not C^3。
