N 种可积 Volterra 系统作为最大超可积哈德米尔系统

可精确求解与可积系统 2025-06-11 v4

摘要

本文 presenting 的结果是对论文 {\it The Volterra Integrable case. Novel analytical and numerical results} (OCNMP Vol.4 (2024) pp 188-211) 中所述结果的自然延伸。该论文重新审视了由 Vito Volterra 于 1937 年引入的哈德米尔 NN 种物种 Lotka-Volterra 系统,可积情况,并提出了一种用于构建运动积分的替代方法并与旧方法进行了比较。本文进一步表明,该 Volterra 所提出的模型经我们所研究的实际上不仅是可积的,而且是最大超可积的,并且可还原为仅有一个自由度的系统,无论考虑多少种物种。我们呈现了解析和数值结果。
