| contents | We study Laguerre isotropic hypersurfaces in the Euclidean space, which are hypersurfaces whose Laguerre form is zero and the eigenvalues of the Laguerre tensor are constant and equal to $λ\geq 0$. We prove a rigidity theorem for the L-isotropic hypersurfaces parametrized by lines of curvature. Moreover, we study the hypersurfaces that are L-isotropic and L-isoparametric simultaneously and we show that for such a hypersurface $λ=0$. We obtain necessary conditions for the existence of L-isotropic hypersurfaces with $λ> 0$ and we prove that a certain function, determined by the radii of curvature of the hypersurface, is bounded above by ${1}/{2λ}$. |
