Conformal Vector Fields and Null Hypersurfaces
(Springer, 2022-05-03)We give conditions for a conformal vector field to be tangent to a null hypersurface. We particularize to two important cases: a Killing vector field and a closed and conformal vector field. In the first case, we obtain a ... -
Contact structures on null hypersurfaces
Atindogbé, Cyriaque; Gutiérrez-López, Manuel
; Hounnonkpe, Raymond; Olea, Benjamín (Elsevier, 2022-08)
The aim of this paper is to show how we can induce contact structures, contact metric structures and Sasaki structures on a null hypersurface from a rigging vector field. We give several explicit examples of this construction ... -
Fostering the cooperative learning of mathematics in engineering schools through the "Teacher-Apprentice" group dynamics
Morales-González, Juan Miguel; Olea, Benjamín; Atencia-Ruiz, Miguel Alejandro; Madrid-Labrador, Nicolás Miguel (2019-05-30)
In this presentation, we report on the experience gained and the results obtained from an educational innovation project that has sought to introduce cooperative learning into the mathematics subjects of the first year of ...
