Popis: We consider Gauss rigidity and Gauss infinitesimal rigidity for hedgehogs of \({\mathbb{R}^{3}}\) (regarded as Minkowski differences of closed convex surfaces of \({\mathbb{R}^{3}}\) with positive Gaussian curvature). Besides, we prove under an appropriate differentiability condition that whenever we perform a deformation of a hedgehog so that its curvature function remains constant, its algebraic volume also remains constant.
