Abstract (in english)
   The form of parabolic lines and caustics in homogeneous generally anisotropic solids can be very complicated but simplifies considerably in homogeneous weakly anisotropic solids. Assuming sufficiently weak anisotropy, no parabolic lines appear on the S1 slowness sheet. Consequently, the corresponding wave sheet displays no caustics or triplications.
