This communication is focused on the study of contractions of certain types of Lie algebras of low dimension, in order to address the implementation of the results to certain physical concepts, such as the boundary process ...

We provide a new construction of Lagrangian surfaces in C2 in terms of two planar curves. When we take such curves as appropriate solutions of the curve shortening problem, including self-shrinking and self-expanding ...

In this talk we will describe the characterization of the chronological relation on doubly warped product spacetimes of the form (a, b) × M1 × M2 with Lorentzian metric g = −dt2 + α1g1 + α2g2, and we will discuss when these ...

Se presenta la clasificación de las hipersuperficies isoparamétricas del espacio hiperbólico complejo CHn, siguiendo el trabajo realizado en J. C. Díaz-Ramos, M. Domínguez-Vázquez, V. Sanmartín-López, Isoparametric hypersurfaces ...

En este trabajo presentamos una primera aproximación al estudio geométrico de la aerodinámica de curvas y superficies. En primer lugar, motivaremos el estudio a partir de situaciones concretas y ejemplos físicos, para ...

Using a correspondence between totally umbilic null hypersurfaces in generalized Robertson-Walker spaces and twisted decompositions of the fibre we show that nullcones are the unique totally umbilic null hypersurfaces in ...

En este trabajo definimos una diferencial de Hopf para superficies lineales de Weingarten que además satisfacen una relación de tipo elíptico al ser vistas como grafo sobre sus planos tangentes. Como consecuencia damos ...

The notion of a uniformly accelerated rectilinear motion of an observer in a general spacetime is analysed in detail. From a geometric viewpoint, a uniformly accelerated observer may be seen as a Lorentzian circle. Finally, ...
