    "abstract": "Wave catastrophes are characterized by logarithmic phase singularities.\nExamples are light at the horizon of a black hole, sound in transsonic fluids,\nwaves in accelerated frames, light in singular dielectrics and slow light close\nto a zero of the group velocity. We show that the wave amplitude grows with a\nhalf-integer power for monodirectional and symmetric wave catastrophes.",
