离散时间二维Toda晶格的直接线性化

Direct linearisation of the discrete-time two-dimensional Toda lattices

Wei Fu

摘要:

在直接线性化框架内研究了离散时间二维Toda格的$A_\infty$型,这使我们能够同时处理这类非线性方程,并构造这些方程的更一般的解.这个模型的周期性减少也被认为是,产生的离散时间的二维Toda晶格的$A_{r-1}^{(1)}$型的$r\geq 2$(这相当于在离散的Gel'fand-Dikii的层次的成员的负流)和它们的可积性。

英文摘要:

The discrete-time two-dimensional Toda lattice of $A_\infty$-type is studied within the direct linearisation framework, which allows us to deal with several nonlinear equations in this class simultaneously and to construct more general solutions of these equations. The periodic reductions of this model are also considered, giving rise to the discrete-time two-dimensional Toda lattices of $A_{r-1}^{(1)}$-type for $r\geq 2$ (which amount to the negative flows of members in the discrete Gel'fand--Dikii hierarchy) and their integrability properties.
