非线性场方程的对称性、守恒荷与 Lax 表示:一种统一方法

Symmetry, Conserved Charges, and Lax Representations of Nonlinear Field Equations: A Unified Approach

C. J. Papachristou

AI总结:

本文研究了守恒律形式非线性场方程中对称性与可积性的非Noether联系,证明仅凭对称性条件即可直接构造Lax pair、双重无限守恒律集合及对称性递归算子,并应用于手征场方程和自对偶Yang-Mills方程。

摘要:

本文研究了守恒律形式的非线性场方程的对称性与可积性之间的某种非 Noether 联系。研究表明,仅凭对称性条件即可直接构造出 Lax pair、双重无限的(通常为非局部的)守恒律集合以及对称性的递归算子。应用包括手征场方程和自对偶 Yang-Mills 方程。

英文摘要:

A certain non-Noetherian connection between symmetry and integrability properties of nonlinear field equations in conservation-law form is studied. It is shown that the symmetry condition alone may lead, in a rather straightforward way, to the construction of a Lax pair, a doubly infinite set of (generally nonlocal) conservation laws, and a recursion operator for symmetries. Applications include the chiral field equation and the self-dual Yang-Mills equation.
