具有多项式相互作用的平面可解动力系统

Solvable Dynamical Systems in the Plane with Polynomial Interactions

Francesco Calogero, Farrin Payandeh

摘要:

本文给出了几个代数可解动力系统的例子,其特征为两个耦合的常微分方程:x_n = P(n)(x1,x2),n = 1,2,其中P(n)(x1,x2)是关于两个因变量x1 = x1(t)和x2 = x2(t)的低次多项式。这些发现是通过最近的一种新的扭曲的技术,以确定动力系统可解的代数运算,明确确定为对应的多项式的系数的演变根据代数可解的(系统)演化方程的零点的时间演化。

英文摘要:

In this paper we report a few examples of algebraically solvable dynamical systems characterized by 2 coupled Ordinary Differential Equations which read as follows: x_n = P(n) (x1, x2) , n = 1, 2 , with P(n) (x1, x2) specific polynomials of relatively low degree in the 2 dependent variables x1 = x1 (t) and x2 = x2 (t) . These findings are obtained via a new twist of a recent technique to identify dynamical systems solvable by algebraic operations, themselves explicitly identified as corresponding to the time evolutions of the zeros of polynomials the coefficients of which evolve according to algebraically solvable (systems of) evolution equations.
