Contractions of certain Lie algebras
(Godel, 2015)
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 ...

An algorithm that constructs irreducible triangulations of once-punctured surfaces
(2013)
A triangulation of a surface is irreducible if there is no edge whose contraction produces another triangulation of the surface. In this work we propose an algorithm that constructs the set of irreducible triangulations ...

Una aproximación geométrica a la aerodinámica de curvas y superficies
(Godel, 2015)
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 ...

Hipersuperficies isoparamétricas en el espacio hiperbólico complejo CHn
(Godel, 2015)
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 ...

Three location tapas calling for CG sauce
(2013)
Based on some recent modelling considerations in location theory we call for study of three CG constructs of Voronoi type that seem not to have been studied much before.

Totally umbilic null hypersurfaces in generalized Robertson-Walker spaces
(Godel, 2015)
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 ...

Causal properties of doubly warped spacetimes
(Godel, 2015)
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 ...

On 4-connected geometric graphs
(2013)
Given a set S of n points in the plane, in this paper we give a necessary and sometimes sufficient condition to build a 4-connected non-crossing geometric graph on S.

Abstract Voronoi diagrams
(2013)
Abstract Voronoi diagrams are a unifying framework that covers many types of concrete Voronoi diagrams. This talk reports on the state of the art, including recent progress.
