报告摘要
We mainly talk about the dynamic stability of the steady 3-D
wave structure of a planar normal shock front intersecting
perpendicularly to a planar solid wall for unsteady potential flows. The
stability problem can be formulated as a free boundary problem of a
quasi-linear hyperbolic equation of second order in a dihedral-space
domain between the shock front and the solid wall. The key difficulty is
brought by the edge singularity of the space domain, the intersection
curve between the shock front and the solid wall. This talk is based on ajoint work with Professor Beixiang Fang，Professor Feimin Huang, and
Professor Wei Xiang.
