Comparison theory of Lorentzian distance with applications to spacelike hypersurfaces
Alías, Luis J.; Hurtado, Ana; Palmer Andreu, Vicente American Institute of Physics (2009)In this paper we summarize some comparison results for the Lorentzian distance function in spacetimes, with applications to the study of the geometric analysis of the Lorentzian distance on spacelike hypersurfaces. In ... -
Geometric analysis of Lorentzian distance function on spacelike hypersurfaces
Alías, Luis J.; Hurtado, Ana; Palmer Andreu, Vicente American Mathematical Society (2010)Abstract. 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 distance to a spacelike hypersurface ... -
Parabolicity criteria and characterization results for submanifoldsof bounded mean curvature in model manifolds with weights
Hurtado, Ana; Palmer Andreu, Vicente; Rosales, César Elsevier (2020)Let P be a submanifold properly immersed in a rotationally symmetric manifold having a pole and endowed with a weight e h. The aim of this paper is twofold. First, by assuming certain control on the h-mean curvature of ... -
Stability numbers in K-contact manifolds
Hurtado, Ana Elsevier (2008)The aim of this paper is to study the stability of the characteristic vector field of a compact K-contact manifold with respect to the energy and volume functionals when we consider on the manifold a two-parameter variation ... -
Torsional rigidity of submanifolds with controlled geometry
Hurtado, Ana; Markvorsen, Steen; Palmer Andreu, Vicente Springer Verlag (2009)We prove explicit upper and lower bounds for the torsional rigidity of extrinsic domains of submanifolds Pm with controlled radial mean curvature in ambient Riemannian manifolds Nn with a pole p and with sectional ...
