Polynomial braid combing
(Oxford University Press, 2018)
We prove that, for n ≥ 3, the minimal dimension of a model of the classifying space of the braid group Bn, and of the pure braid group Pn, with respect to the family of virtually cyclic groups is n.

A closed form for slant submanifolds of generalized Sasakian space forms
(MDPI, 2019-12-13)
The Maslov form is a closed form for a Lagrangian submanifold of Cm, and it is a conformal form if and only if M satisfies the equality case of a natural inequality between the norm of the mean curvature and the scalar ...

Quasi-isometries and proper homotopy: The quasi-isometry invariance of proper 3-realizability of groups
(American Mathematical Society, 2019-04-01)
We recall that a finitely presented group G is properly 3-realizable if for some finite 2-dimensional CW-complex X with π1(X) ∼= G, the universal cover X has the proper homotopy type of a 3-manifold. This purely ...

Minimal linear representations of the low-dimensional nilpotent lie algebras
(2008)
The main goal of this paper is to compute a minimal matrix representation for each non-isomorphic nilpotent Lie algebra of dimension less than 6. Indeed, for each of these algebras, we search the natural number n ∈ N \ ...

Pyramidal values
(Springer, 2014-06)
We propose and analyze a new type of values for cooperative TU-games, which we call pyramidal values. Assuming that the grand coalition is sequentially formed, and all orderings are equally likely, we define a pyramidal ...

Generating families of surface triangulations. The case of punctured surfaces with inner degree at least 4
(2015)
We present two versions of a method for generating all triangulations of any punctured surface in each of these two families: (1) triangulations with inner vertices of degree ≥ 4 and boundary vertices of degree ≥ 3 and (2) ...

100 años de derechos : la primera mujer española doctora en física
(Unidad para la Igualdad, Universidad de Sevilla, 2010)
En este año en el que se celebra el II Congreso Universitario Nacional “Investigación y Género” en la Universidad de Sevilla, se cumple el centenario de la Real Orden del Ministerio de Instrucción Pública y Bellas Artes ...

Willmore Tori in a wide family of conformal structures on odd dimensional spheres
(Rocky Mountain Mathematics Consortium, 2000)
We obtain a variable reduction principle for the Willmore variational problem in an ample class of conformal structures on S2n+1. This variational problem is transformed into another one, associated with an elastic-energ ...

Generalized S-space-forms
(2013)
We introduce and study generalized S-space-forms. Moreover, we investigate generalized S-space-forms endowed with an additional structure and we obtain some obstructions for them to be S-manifolds
