【 摘 要 】
Parts of the Brunn-Minkowski theory can be extended to hedgehogs, which areenvelopes of families of affine hyperplanes parametrized by their Gauss map.F. Fillastre introduced Fuchsian convex bodies, which are theclosed convex sets of Lorentz-Minkowski space that are globally invariantunder the action of a Fuchsian group. In this paper, we undertake a study ofplane Lorentzian and Fuchsian hedgehogs. In particular, we prove theFuchsian analogues of classical geometrical inequalities (analogues whichare reversed as compared to classical ones).
