摘要:
我们描述了Monge-Ampère偏微分方程与一阶拉格朗日量框架下强逆变分问题局部可解性的一个必要条件。该条件基于比较一阶射丛上的有效微分形式。为说明并应用我们的方法,我们在实四维流形上研究了线性Klein-Gordon方程、Plebański的第一与第二天堂方程、Grant方程以及Husain方程。文中还阐述了构建这些方程多辛表述的两种途径。
英文摘要:
We describe a necessary condition for the local solvability of the strong inverse variational problem in the context of Monge-Ampère partial differential equations and first-order Lagrangians. This condition is based on comparing effective differential forms on the first jet bundle. To illustrate and apply our approach, we study the linear Klein-Gordon equation, first and second heavenly equations of Plebański, Grant equation, and Husain equation, over a real four-dimensional manifold. Two approaches towards multisymplectic formulation of these equations are described.
