离散变分系统的可积性。八面体关系

On integrability of discrete variational systems. Octahedron relations

Raphael Boll, Matteo Petrera, Yuri B. Suris

摘要:

我们阐明所谓的角方程的一致性,这是基本的构建块的欧拉-拉格朗日方程的二维多拉格朗日问题。我们表明,它们的一致性可以从两个独立的八面体关系的存在。我们给出明确的公式的八面体关系的角方程。

英文摘要:

We elucidate consistency of the so-called corner equations which are elementary building blocks of Euler-Lagrange equations for two-dimensional pluri-Lagrangian problems. We show that their consistency can be derived from the existence of two independent octahedron relations. We give explicit formulas for octahedron relations in terms of corner equations.
