Abstract Rychlik Rychlik will investigate the following problems: The existence of special classes of solutions in non-linear difference equations and ordinary differential equations which correspond to homoclinic and heteroclinic connections. The existence of algebraic integrals for a class of symplectic maps. The measure of periodic trajectories in billiard systems. The existence of traveling wave and breather solutions to PDEs. Development and implementation of algorithms for dealing with systems of multi-variate polynomial equations with many parameters that often arise in applications. The problems selected for this project generally invite the use of techniques from algebraic geometry and complex analysis. The main objective of the current project is to show that advanced techniques from these fields are useful in solving problems of dynamics. A result of this research will be a suite of algebraic and complex-analytic methods general enough to be applied to other problems.

抽象Rychlik Rychlik将调查以下问题：存在特殊类的解决方案，在非线性差分方程和常微分方程，对应于同宿和异宿连接。 一类辛映射代数积分的存在性。 台球系统中周期轨线的测度。 偏微分方程行波解和呼吸子解的存在性。 开发和实现用于处理在应用中经常出现的具有多个参数的多元多项式方程组的算法。 为这个项目选择的问题通常邀请使用代数几何和复分析的技术。 当前项目的主要目标是表明这些领域的先进技术在解决动力学问题方面是有用的。这项研究的结果将是一套代数和复分析方法一般足以适用于其他问题。
