WebThe second H. Weyl curvature invariant of a Riemannian manifold, denoted h4, is the second curvature invariant which appears in the well known tube formula of H. Weyl. It coincides with the Gauss-Bonnet integrand in dimension 4. A crucial property of h4 is that it is nonneg-ative for Einstein manifolds, hence it provides a geometric obstruction ... WebIn computational anatomy, organ’s shapes are often modeled as deformations of a reference shape, i.e., as elements of a Lie group. To analyze the variability of the human anatomy in this framework, we need to perform statistics on Lie groups. A Lie group is a manifold with a consistent group structure. Statistics on Riemannian manifolds have been well studied, … tpain racing setup
