AI总结:

研究具有多项式非线性的周期色散广义Benjamin-Ono方程,建立其非线性平滑性质,并在色散足够大时获得新的局部适定性结果,同时改进了不可积五阶KdV方程的已知结果。

摘要:

我们考虑具有多项式非线性的周期色散广义Benjamin-Ono方程。我们建立了这些方程的非线性平滑性质,根据该性质,解与线性演化之间的差值比初始数据更平滑。此外,当色散足够大时,我们为这些方程建立了新的局部适定性结果。我们的方法还改进了一类不可积五阶KdV方程的已知局部适定性结果。

英文摘要:

We consider the periodic dispersion generalized Benjamin-Ono equations with polynomial nonlinearity. We establish the nonlinear smoothing properties of these equations, according to which the difference between the solution and the linear evolution is smoother than the initial data. In addition, we establish new local well-posedness results for these equations when the dispersion is sufficiently large. Our method also improves known local well-posedness results for a class of non-integrable fifth-order KdV equations.
