Exploring new extrinsic upper bounds on the first eigenvalue of the Laplace operator for compact submanifolds in Euclidean spaces
Francisco J. Palomo, Alfonso Romero
Upper bounds of the first non-trivial eigenvalue of the Laplace operator of a compact submanifold of Euclidean space , by means of a new technique, are obtain…

On spacelike surfaces in 4-dimensional Lorentz-Minkowski spacetime through a lightcone
Francisco J. Palomo, Alfonso Romero
On any spacelike surface in a lightcone of four dimensional Lorentz-Minkowski space a distinguished smooth function is considered. It is shown how both extrinsic and intrinsic geom…
