1. Universalidad y aplicabilidad de las matemáticas en Wittgenstein y el empirismo logicista - Barceló Aspeitia, Axel Arturo
//// Abstract: This paper studies the notions of universality and applicability of mathematics in the writings of Wittgenstein’s middle period. Against a common opinion, the author argues that mathematics is not a science of the most abstract and general. By focusing on the notion of grammar in Philosophical observations and Philosophical grammar , the author holds that one can account for the use of mathematics in extra mathematical contexts without resorting to what he calls the myth of universality.

4. Hilbert, Kant y el fundamento de las matemáticas - Torres Alcaraz, Carlos
//// Abstract: This paper looks into Hilbert’s thought about mathematics and explores its relation which the philosophy of Kant. The focus of the research is in the role of axiomatic thinking and logical analysis in foundational studies. The paper concentrates mainly in Hilbert’s research regarding the foundations of geometry, and follows his main lines of thought up to his programme, which revolves around a consistency proof for the axioms of classical mathematics. A final analysis allows us to conclude that for him mathematics is, in a broad sense, “the science of that which is possible” in this point, Hilbert diverges...

11. Proximal calculus on Riemannian manifolds - Ferrera Cuesta, Juan; Azagra Rueda, Daniel
We introduce a proximal subdifferential and develop a calculus for nonsmooth functions defined on any Riemannian manifold M. We give some applications of this theory, concerning, for instance, a Borwein-Preiss type variational principle on a Riemannian manifold M, as well as differentiability and geometrical properties of the distance function to a closed subset C of M.

14. Modelizando el cálculo de varias variablEEES en el aula - Aragón Ángel, María Ángeles; Cubarsí Morera, Rafael
La implantación de la modelización matemática en el ámbito del Espacio Europeo de Educación Superior (EEES) necesita de una revisión y adaptación de los contenidos yestrategias para abordar las asignaturas, en particular, aquellas más teóricas yabstractas para fomentar su carácter interdisciplinario. Se presenta una nuevapropuesta metodológica para la asignatura de Análisis Vectorial (cálculo multivariable)ofertada durante los últimos años por l’Escola Tècnica Superior d’Enginyeria deTelecomunicacions de Barcelona (ETSETB) de la Universitat Politècnica de Catalunya(UPC). Es una de las asignaturas de la fase selectiva de dicha titulación, con 4.5créditos de teoría y 3 de prácticas (repartidos entre problemas y laboratorios).

15. Proteine Bolognese - Cubarsí Morera, Rafael; Vázquez, Esther; Villaverde, Antonio
Se modeliza la penetración de una versión modificada de la proteína verde fluorescentellamada GFP en el citoplasma y el núcleo de una célula de mamífero. El modelo matemático proporciona una primera aproximación al experimento, con una disminución progresiva de la tasa de fluorescencia a medida que la luminosidad total va aumentando hasta saturarse. Sin embargo, se detecta una desviación localizada del modelo propuesto, debida a un proceso que no se realiza de forma totalmente diferenciable.El fenómeno es explicable a partir de la irrupción brusca de GFP en el citoplasma y elnúcleo por la debilitación o ruptura de sus membranas, y...

16. Three kinematical methods to identify local galactic structures - Cubarsí Morera, Rafael; Alcobé López, Santiago; Vidojevic, S.; Ninkovic, S.
Method one: by combining a sampling parameter related to an isolating integral of the stellar motion, an optimisation ofthe mixture approach, and a maximisation of the partition entropy for the constituent populations of the stellar sample.Method two: by segregating into different kinematical components in terms of the stellar orbital parameters.Method three: by approaching a maximum entropy velocity distribution to samples selected in terms of stellar eccentricitylayers.Working samples: HIPPARCOS and Geneva-Copenhagen survey catalog.Results: kinematical characterisation of large-scale structures, such as thin disc, thick disc and halo, and identification ofsmall-scale structures, such as moving groups in the solar neighbourhood.Consequences: confirmation of the...

17. Overlapping community search for social networks - Padrol Sureda, Arnau; Perarnau Llobet, Guillem; Pfeifle, Julián; Muntés Mulero, Víctor
Finding decompositions of a graph into a family of clusters is crucial to understanding its underlying structure.While most existing approaches focus on partitioning the nodes, real-world datasets suggest the presence of overlapping communities. We present OCA, a novel algorithm to detect overlapped communities in large data graphs. It outperforms previous proposals in terms of execution time, and efficiently handles large graphs containing more than 108 nodes and edges.

18. Gale duality bounds on the location of roots of polynomials with nonnegative coefficients - Pfeifle, Julián
We bound the location of roots of polynomials that have nonnegativecoefficients with respect to a fixed but arbitrary basis of the vector space of polynomials of degree at most d. For this, we interpret the basis polynomials as vector fields in the real plane, and at each point in the plane analyze the combinatorics of the Gale dual vector configuration. This approach permits us to incorporatearbitrary linear equations and inequalities among the coefficients in a unified manner to obtain more precise bounds on the locationof roots. We apply our technique to bound the location of roots of Ehrhart and chromatic...

19. Kalai's squeezed three-spheres are polytopal - Pfeifle, Julián
In 1988, Kalai [5] extended a construction of Billera and Lee to produce many triangulated(d−1)-spheres. In fact, in view of upper bounds on the number of simplicial d-polytopes by Goodman and Pollack [2,3], he derived that for every dimension d ≥ 5, most of these(d−1)-spheres are not polytopal. However, for d=4, this reasoning fails. We can now show that, as already conjectured by Kalai, all of his 3-spheres are in fact polytopal. We also give a shorter proof for Hebble and Lee’s result [4] that the dual graphs of these 4-polytopes are Hamiltonian.

20. On the monotone upper bound problem - Pfeifle, Julián; Ziegler, Günter M.
The Monotone Upper Bound Problem asks for the maximal number M(d,n) of vertices on a strictly-increasing edge-path on a simple d-polytope with n facets. More specifically, it asks whether the upper boundM(d,n) ≤ Mubt(d,n)provided by McMullen’s (1970) Upper Bound Theorem is tight, where Mubt(d,n) is the number of vertices of a dual-to-cyclic d-polytope with n facets.It was recently shown that the upper bound M(d,n) ≤ Mubt(d,n) holds with equality for small dimensions (d ≤ 4: Pfeifle, 2003) and for small corank (n ≤ d + 2: Gärtner et al., 2001). Here we prove that it is not tight in general:...
