具有叠加公式的离散矩阵Riccati方程

Discrete matrix Riccati equations with superposition formulas

Alexei V. Penskoi, Pavel Winternitz

摘要:

如果一个常微分方程的通解可以表示为有限个特解的函数,则称该方程具有叠加公式。具有叠加公式的非线性常微分方程包括矩阵Riccati方程。这里我们将描述保留叠加公式的黎卡提方程的离散化。该方法是一般的,足以包括$q$ -衍生物和标准的离散衍生物。

英文摘要:

An ordinary differential equation is said to have a superposition formula if its general solution can be expressed as a function of a finite number of particular solution. Nonlinear ODE's with superposition formulas include matrix Riccati equations. Here we shall describe discretizations of Riccati equations that preserve the superposition formulas. The approach is general enough to include $q$-derivatives and standard discrete derivatives.
