多项式动力系统半代数不变量的计算

Computing Semi-algebraic Invariants for Polynomial Dynamical Systems

Jiang Liu, Naijun Zhan, Hengjun Zhao

摘要:

本文考虑了具有定义域和初始条件的多项式动力系统(PDS)的不变量的一个扩展概念,并建立了检验这类PDS的半代数不变量(SAI)的一个可靠而完备的判据。其主要思想是将相关的动力学性质编码为发生在SAI中的多项式的高阶李导数的条件。该准则的直接结果是基于模板假设和半代数约束求解的相对完整的SAI生成方法。相对完整性意味着如果有一个以预定义模板形式存在的SAI,那么我们的方法确实可以使用这个模板找到一个SAI。

英文摘要:

In this paper, we consider an extended concept of invariant for polynomial dynamical system (PDS) with domain and initial condition, and establish a sound and complete criterion for checking semi-algebraic invariants (SAI) for such PDSs. The main idea is encoding relevant dynamical properties as conditions on the high order Lie derivatives of polynomials occurring in the SAI. A direct consequence of this criterion is a relatively complete method of SAI generation based on template assumption and semi-algebraic constraint solving. Relative completeness means if there is an SAI in the form of a predefined template, then our method can indeed find one using this template.
