我们描述了最近由动力系统/埃文斯函数技术获得的粘性和无粘性爆震波的稳定性和行为的分析和数值结果,这些技术用于研究激波和反应扩散波。在第一部分中,我们给出一维微扰的粘性和非粘性结果的广泛描述;第二部分重点研究了多维无粘高频稳定性问题以及拐点理论/WKB展开中的相关问题。
We describe recent analytical and numerical results on stability and behavior of viscous and inviscid detonation waves obtained by dynamical systems/Evans function techniques like those used to study shock and reaction diffusion waves. In the first part, we give a broad description of viscous and inviscid results for 1D perturbations; in the second, we focus on inviscid high-frequency stability in multi-D and associated questions in turning point theory/WKB expansion.
