一阶欧拉-拉格朗日方程及其应用

The First-Order Euler-Lagrange equations and some of their uses

C. Adam, F. Santamaria

摘要:

在许多非线性场论中,可以通过降低原始欧拉-拉格朗日方程的阶数来找到相关解,例如,到一阶方程(Bogomolnyi方程,自对偶方程等)。在这里,我们概括,进一步发展和应用一个特定的方法,减少非线性场方程的阶,尽管它的系统和多功能的字符,是不广为人知的。

英文摘要:

In many nonlinear field theories, relevant solutions may be found by reducing the order of the original Euler-Lagrange equations, e.g., to first order equations (Bogomolnyi equations, self-duality equations, etc.). Here we generalise, further develop and apply one particular method for the order reduction of nonlinear field equations which, despite its systematic and versatile character, is not widely known.
