摘要:

我们研究了一类带有通常光滑非线性项g(u)的广义Camassa-Holm-Kadomtsev-Petviashvili(CH-KP)方程解的爆发行为和Liouville型定理。首先,利用连续性方法,我们建立了一个与初始数据正则性指数无关的爆发准则。在假设g'(u)有界的情况下,我们通过特征线、先验估计和Riccati不等式证明了爆发定理和加权爆发结果。此外,我们将这些爆发结果扩展到g'(u)被多项式控制的情形,这包括典型的非线性项,如g(u)=κu+3u²对于经典CH-KP方程。此外,在条件g(u)≥γu²且u≠0,g(u)>γu²的情况下,建立了Liouville型唯一性定理。

英文摘要:

We investigate the blow-up behavior and Liouville-type theorems of solutions to a class of generalized Camassa-Holm-Kadomtsev-Petviashvili (CH-KP) equations with a generally smooth nonlinear term $g(u)$. First, using the continuation method, we establish a blow-up criterion that is independent of the regularity index of initial data. Under the assumption that $ g'(u)$ is uniformly bounded, we prove the blow-up theorem and a weighted blow-up result by means of characteristic lines, a priori estimates and the Riccati inequality. Moreover, we extend these blow-up results to the setting where $g'(u)$ is polynomially controlled, which includes typical nonlinearities such as $ g(u)=κu+3u^2 $ for the classical CH-KP equations. Furthermore, a Liouville-type uniqueness theorem is established under the condition $g(u) \geq γu^2$ with $u \neq 0$, $g(u)>γu^2$.
