This project seeks to deepen understanding of how complex systems may be significantly changed by incremental changes to ambient conditions. Mathematical models of complex systems (climate change processes, optimal driving strategies, efficient distribution policies, effective search routines) often depend on key parameters. If small perturbations to the parameters cause large changes to the solution, then the perturbations are said to be singular. This project aims to reveal the underlying mathematical structures and develop new computational algorithms to analyse a general class of perturbed systems both locally near an isolated singularity and globally. It plans to use these algorithms to solve systems of equations, calculate generalised inverse operators, examine perturbed Markov processes, and estimate exit times from meta-stable states in stochastic population dynamics.

这个项目寻求加深对复杂系统如何通过环境条件的增量变化而显著改变的理解。复杂系统的数学模型(气候变化过程、最优驾驶策略、有效的分配政策、有效的搜索例程)往往取决于关键参数。如果对参数的微小扰动导致解的大变化，则称这种扰动是奇异的。这个项目旨在揭示潜在的数学结构，并开发新的计算算法来分析一类一般的扰动系统，包括局部的孤立奇点和全局的扰动系统。它计划使用这些算法来求解方程组，计算广义逆算子，检查扰动的马尔可夫过程，并估计随机种群动力学中亚稳定状态的退出时间。
