报告题目：A Novel Kernel Based Fictitious Domain Method

摘要：A novel numerical method is discussed which unifies so-called fictitious domain methods with so-called mesh-free methods and allows some analysis since it fits into the framework of kernel-based methods. It will be demonstrated that it delivers a numerical method that is very easily implemented, applies to a wide range of problems (on complex domains, with general boundary conditions and non-constant coefficients) , and allows for tunable high order of accuracy.

报告题目：Solutions and Stability Questions for a Parabolic Oscillator

摘要：A simple model is presented which exhibits interesting non-trivial dynamic behavior. It will be shown to possess periodic solutions in spite of being purely diffusive in nature. Stability of the trivial solution up to the Hopf bifurcation point yielding the periodic solution will be discussed.

报告题目：A Simple Diffusive Mechanism Can Explain Oscillations

摘要：In this talk I shall first present a thermostat model. Interestingly, the model shows that a simple diffusive mechanism can explain oscillations and may help explain periodic behavior in other fields such as biology.
