关于质量临界的广义KdV方程

On the mass-critical generalized KdV equation

Rowan Killip, Soonsik Kwon, Shuanglin Shao, Monica Visan

摘要:

考虑实值函数$u(t,x)$的质量临界广义Korteweg-de Vries方程$$(\partial_t + \partial_{xxx})u=\pm \partial_x(u^5)$$.我们证明了如果该方程的整体适定性和散射猜想不成立,那么在质量临界非线性薛定谔方程$(-i\partial_t + \partial_{xx})u=\pm (|u|^4u)$的整体适定性和散射猜想得到肯定回答的条件下,质量临界广义KdV方程存在一个极小质量爆破解,该解是模对称的概周期解.此外,我们可以保证,这个最小质量爆破解决方案是一个自相似的解决方案,一个孤立子的解决方案,或双高低频级联解决方案。

英文摘要:

We consider the mass-critical generalized Korteweg--de Vries equation $$(\partial_t + \partial_{xxx})u=\pm \partial_x(u^5)$$ for real-valued functions $u(t,x)$. We prove that if the global well-posedness and scattering conjecture for this equation failed, then, conditional on a positive answer to the global well-posedness and scattering conjecture for the mass-critical nonlinear Schrödinger equation $(-i\partial_t + \partial_{xx})u=\pm (|u|^4u)$, there exists a minimal-mass blowup solution to the mass-critical generalized KdV equation which is almost periodic modulo the symmetries of the equation. Moreover, we can guarantee that this minimal-mass blowup solution is either a self-similar solution, a soliton-like solution, or a double high-to-low frequency cascade solution.
