A Lagrangian Approach to Weakly Coupled Hamilton-Jacobi Systems

H. Mitake, A. Siconolfi, H. V. Tran, N. Yamada

摘要:

我们研究了一类弱耦合Hamilton-Jacobi系统,具体目的是在弱KAM理论的精神下进行定性分析。我们的主要成就是定义了一个家庭的相关行动泛函包含拉格朗日从系统的哈密顿对偶。我们用它们来表征,通过适当的估计,系统的所有子解,并明确表示一些子解享受额外的极大值属性。我们分析的一个关键步骤是把问题放在一个合适的随机框架中。只需要测度论的一些基本知识,没有概率背景的读者也可以使用演示文稿。

英文摘要:

We study a class of weakly coupled Hamilton-Jacobi systems with a specific aim to perform a qualitative analysis in the spirit of weak KAM theory. Our main achievement is the definition of a family of related action functionals containing the Lagrangians obtained by duality from the Hamiltonians of the system. We use them to characterize, by means of a suitable estimate, all the subsolutions of the system, and to explicitly represent some subsolutions enjoying an additional maximality property. A crucial step for our analysis is to put the problem in a suitable random frame. Only some basic knowledge of measure theory is required, and the presentation is accessible to readers without background in probability.
