摘要

我们考虑 n 维阶梯系统，即形式为（\mathop {\dot{x}}\nolimits_{i} = x_{i}\displaystyle\sum_{j = 1}^{n} 的均相微分系统。\,(i + 1 - j)x_{j},\quad i = 1, \ldots ,n\) 由 Imai 和 Hirata 引入，用于研究一类新的 Lotka-Volterra 系统的可整性。在此，我们将描述这些 Lotka-Volterra 系统在任意维度下的动力学特性。

The Dynamics of the Ladder System

We consider the n-dimensional ladder system, that is the homogeneous differential systems of the form \(\mathop {\dot{x}}\nolimits_{i} = x_{i}\displaystyle\sum_{j = 1}^{n} \,(i + 1 - j)x_{j},\quad i = 1, \ldots ,n\) introduced by Imai and Hirata for studying the integrability of a new class of Lotka–Volterra systems. Here we describe the dynamics of these Lotka–Volterra systems in arbitrary dimension.
