关于不变量和禁止集

On invariants and forbidden sets

Frank J. Palladino

摘要:

本文对有理差分方程引入了六个新的代数不变式。我们使用这些不变量在每种情况下执行降阶。这种降阶允许我们在每种情况下找到禁止集。这六种情况包括两个阶数大于1的线性分数阶有理差分方程。在所有六种情况下,我们给出了一个封闭形式的解决方案,所有的初始条件是不是在禁止集。在所有六种情况下,初始条件和参数被假定为任意的复数。

英文摘要:

We introduce six new algebraic invariants for rational difference equations. We use these invariants to perform a reduction of order in each case. This reduction of order allows us to find forbidden sets in each case. These six cases include two linear fractional rational difference equations of order greater than one. In all six cases, we give a closed form solution for all initial conditions which are not in the forbidden set. In all six cases, the initial conditions and parameters are assumed to be arbitrary complex numbers.
