离散Toda场方程

Discrete Toda Field Equations

R. S. Ward

摘要:

有二维户田场方程对应于每个(有限或仿射)李代数。本说明中所解决的问题是,是否存在这些可积离散版本。结果表明,对于某些代数(如$A_n$,$A_n^{(1)}$和$B_n$),存在有解,但有些系统定义在半平面上,而不是全二维格上.

英文摘要:

There are two-dimensional Toda field equations corresponding to each (finite or affine) Lie algebra. The question addressed in this note is whether there exist integrable discrete versions of these. It is shown that for certain algebras (such as $A_n$, $A_n^{(1)}$ and $B_n$) there do, but some of these systems are defined on the half-plane rather than the full two-dimensional lattice.
