The classification of complete stable area-stationary surfaces in the Heisenberg group
Ana Hurtado, Manuel Ritoré, César Rosales
We prove that any complete, orientable, connected, stable area-stationary surface in the sub-Riemannian Heisenberg group is either a Euclidean plane or congrue…
Torsional rigidity of submanifolds with controlled geometry
A. Hurtado, S. Markvorsen, V. Palmer
We prove explicit upper and lower bounds for the torsional rigidity of extrinsic domains of submanifolds P^m with controlled radial mean curvature in ambient Riemannian manifolds N…
Instability of Hopf vector fields on Lorentzian Berger spheres
Ana Hurtado
In this work, we study the stability of Hopf vector fields on Lorentzian Berger spheres as critical points of the energy, the volume and the generalized energy. In order to do so,…
Geometric analysis of Lorentzian distance function on spacelike hypersurfaces
Luis J. Alias, Ana Hurtado, Vicente Palmer
Some analysis on the Lorentzian distance in a spacetime with controlled sectional (or Ricci) curvatures is done. In particular, we focus on the study of the restriction of such dis…
