12 p, 1.5 MB EM for phylogenetic topology reconstruction on nonhomogeneous data / Ibáñez-Marcelo, Esther (Centre de Recerca Matemàtica) ; Casanellas i Rius, Marta (Universitat Politècnica de Catalunya. Departament de Matemàtica Aplicada I)
The reconstruction of the phylogenetic tree topology of four taxa is, still nowadays, one of the main challenges in phylogenetics. Its difficulties lie in considering not too restrictive evolutionary models, and correctly dealing with the long-branch attraction problem. [...]

22 p, 505.3 KB Dynamics, integrability and topology for Lotka-Volterra Hamiltonian systems in R^4 / Llibre, Jaume (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Xiao, Dongmei (Shanghai Jiao Tong University. School of Mathematical Sciences)
In this paper first we give the sufficient and necessary conditions in order that two classes of polynomial Kolmogorov systems in \R_ ^4 are Hamiltonian systems. After we study the integrability of these Hamiltonian systems in the Liouville sense. [...]

29 p, 982.5 KB Topology of singular holomorphic foliations along a compact divisor / Marín Pérez, David (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Mattei, Jean-François (Institut de Mathématiques de Toulouse)
We consider a singular holomorphic foliation F defined near a compact curve C of a complex surface. Under some hypothesis on (F;C) we prove that there exists a system of tubular neighborhoods U of a curve D containing C such that every leaf L of Fj(U\D) is incompressible in U\D. [...]

Let X be a zero-dimensional, Hausdorff topological space and K a field with a non-trivial, non-archimedean valuation under which it is complete. Then BC(X) is the vector space of the bounded continuous functions from X to K. [...]

In this paper, a new method for image deformation is presented. It is based upon decomposition of the deformation problem into basic physical laws. Unlike other methods that solve a differential or an energetic formulation of the physical laws involved, we encode the basic laws using computational algebraic topology. [...]

13 p, 176.9 KB Harmonic maps and the topology of manifolds with positive spectrum and stable minimal hypersurfaces / Wang, Q.
In this paper, we prove two Liouville theorems for harmonic maps and apply them to study the topology of manifolds with positive spectrum and stable minimal hypersurfaces in Riemannian manifolds with non-negative bi-Ricci curvature.

Let d be an integer, and let E be a nonempty closed subset of Rn. Assume that E is locally uniformly non flat, in the sense that for x ∈ E and r > 0 small, E∩B(x, r) never stays ε0r-close to an affine d-plane. [...]

13 p, 402.8 KB Proposta d'una nova topologia de xarxa P2P : Constant Rectangle / Solís Gilabert, Roger ; Bartrina Rapesta, Joan, dir. (Universitat Autònoma de Barcelona. Departament d'Enginyeria de la Informació i de les Comunicacions) ; Universitat Autònoma de Barcelona. Escola d'Enginyeria
Des de la creació de Napster al 1999, les xarxes Peer-to-Peer (P2P) han vist augmentada la seva popularitat amb el pas del temps, sobretot en l'àmbit de la compartició i intercanvi d'arxius. Tenint en compte que en una xarxa P2P els usuaris tenen la possibilitat de comunicar-se entre ells de manera directa, és important definir una topologia de xarxa que organitzi de quina manera es realitzaran aquestes comunicacions. [...]
Since the creation of Napster in 1999, Peer-to-Peer (P2P) networks have become more popular over time, especially in the area of sharing and exchange of files. Given that in P2P networks, users have the possibility to communicate directly to each other, it is important to define a network topology to organize how communications among users will be made. [...]

4 p, 102.2 KB Topologia de varietats [100114] / Pitsch, Wolfgang ; Durán Batalla, Juan Luis ; Universitat Autònoma de Barcelona. Facultat de Ciències
Ever since the concept of homeomorphism was clearly defined, the "ultimate" problem in topology has been to classify topological spaces ''up to homeomorphism". That this was a hopeless undertaking was very soon apparent, the subspaces of the plane R2 being an obvious example. [...]
