Toda方程的直接“延迟”约化

Direct "Delay" Reductions of the Toda Equation

Nalini Joshi

摘要:

本文提出了一种新的求Toda方程约化的直接方法。我们发现一个典型的和完整的类的所有可能的减少在一定的假设。由此产生的方程是常微分-差分方程,有时称为延迟微分方程。这类方程的代表假设是一个新的版本的经典潘勒韦方程。与此方程相关的拉克斯对也是通过约化得到的。

英文摘要:

A new direct method of obtaining reductions of the Toda equation is described. We find a canonical and complete class of all possible reductions under certain assumptions. The resulting equations are ordinary differential-difference equations, sometimes referred to as delay-differential equations. The representative equation of this class is hypothesized to be a new version of one of the classical Painlevé equations. The Lax pair associated to this equation is obtained, also by reduction.
