AI总结:

本文研究了二维卡多莫特塞夫-彼得萨夫斯基 II 方程的临界长度问题,通过推导可观察性不等式,实现了线性系统的精确边界可控性和边界指数稳定化。

摘要:

Korteweg-de Vries 方程的临界长度现象已广为人知;然而在更高维度中,这一现象尚不明确。本文探讨了卡多莫特塞夫-彼得萨夫斯基方程的这一属性,这是 Korteweg-de Vries 方程的二维推广。具体而言,我们为该方程推导了可观察性不等式,这使得我们能够推断出在空间域长度避免某些特定值时,线性系统的精确边界可控性和边界指数稳定化。据我们所知,我们的工作通过识别二维卡多莫特塞夫-彼得萨夫斯基方程的一组临界长度,引入了新的结果。

英文摘要:

The critical length phenomenon of the Korteweg-de Vries equation is well known; however, in higher dimensions, it is unknown. This work explores this property in the context of the Kadomtsev-Petviashvili equation, a two-dimensional generalization of the Korteweg-de Vries equation. Specifically, we demonstrate observability inequalities for this equation, which allow us to deduce the exact boundary controllability and boundary exponential stabilization of the linear system, provided that the spatial domain length avoids certain specific values, a direct consequence of the Paley-Wiener theorem. To the best of our knowledge, our work introduces new results by identifying a set of critical lengths for the two-dimensional Kadomtsev-Petviashvili equation.
