Connections compatible with tensors. A characterization of left-invariant Levi--Civita connections in Lie groups
Paolo Piccione, Daniel V. Tausk
Symmetric connections that are compatible with semi-Riemannian metrics can be characterized using an existence result for an integral leaf of a (possibly non integrable) distributi…
Conjugate points and Maslov index in locally symmetric semi-Riemannian manifolds
Miguel Angel Javaloyes, Paolo Piccione
We study the singularities of the exponential map in semi Riemannian locally symmetric manifolds. Conjugate points along geodesics depend only on real negative eigenvalues of the c…
On the Patterns of Principal Curvature Lines around a Curve of Umbilic Points
Ronaldo Garcia, Jorge Sotomayor
In this paper is studied the behavior of principal curvature lines near a curve of umbilic points of a smooth surface.
Volume-minimizing foliations on spheres
Fabiano Brito, David L. Johnson
The volume of a k-dimensional foliation in a Riemannian manifold is defined as the mass of image of the Gauss map, which is a map from M to the Grassmann bund…
