波浪灾难分类
Towards a classification of wave catastrophes
摘要：
波浪灾变的特征是对数相位奇异性。例如黑洞视界的光，跨音速流体中的声音，加速系中的波，奇异群速度中的光和群速度接近零的慢光。我们发现，波的振幅增长与半整数幂的单向和对称波的灾难。
英文摘要：
Wave catastrophes are characterized by logarithmic phase singularities. Examples are light at the horizon of a black hole, sound in transsonic fluids, waves in accelerated frames, light in singular dielectrics and slow light close to a zero of the group velocity. We show that the wave amplitude grows with a half-integer power for monodirectional and symmetric wave catastrophes.
