Anisotropic wavefronts and Laguerre geometry

Source abstract

Motivated by the study of wavefronts in anisotropic media, we propose an incidence geometry for anisotropic spheres in a Finsler-Minkowski space. An anisotropic version of the Laguerre functional is considered. In some circumstances, this functional can be used to determine that two wavefronts observed at distinct times in a homogeneous anisotropic medium do not originate from the same source.
