Previous issue date: 2008 / Resumo: Neste trabalho, apresentamos um algoritmo para um complexo de cadeias C e sua diferencial dada por uma matriz de conexão _ que determina uma seqüência espectral associada (Er, dr). Mais especificamente, um sistema gerador de Er em termos da base original de C é obtido bem como a identificação de todas as diferenciais dr p : Er p ! Er pr. Explorando a implicação dinâmica da diferencial não nula, mostramos a existência de um caminho unindo a singularidade que gera E0 p e a singularidade que gera E0 pr no caso em que a conexão direta pelo fluxo não existe. Este caminho é composto pela justaposição de órbitas do fluxo e do fluxo reverso e prova ser importante em algumas aplicações / Abstract: In this work, we present an algorithm for a chain complex C and its di_erential given by a connection matrix _ which determines an associated spectral sequence (Er, dr). More specifically, a system spanning Er in terms of the original basis of C is obtained as well as the identi_cation of all di_erentials dr p : Er p ! Er pr. In exploring the dynamical implication of a nonzero di_erential, we prove the existence of a path joining the singularities generating E0 p and E0 pr in the case that a direct connection by a _ow line does not exist. This path is made up of juxtaposed orbits of the _ow and of the reverse _ow and which proves to be importantin some applications / Doutorado / Geometria e Topologia/Sistemas Dinamicos / Doutor em Matemática

Cohomology and Ktheory of aperiodic tilingsSavinien, Jean P.X. 19 May 2008 (has links)
We study the Ktheory and cohomology of spaces of aperiodic and repetitive tilings with finite local complexity. Given such a tiling, we build a spectral sequence converging to its Ktheory and define a new cohomology (PV cohomology) that appears naturally in the second page of this spectral sequence. This spectral sequence can be seen as a generalization of the LeraySerre spectral sequence and the PV cohomology generalizes the cohomology of the base space of a Serre fibration with local coefficients in the Ktheory of its fiber. We prove that the PV cohomology of such a tiling is isomorphic to the Cech cohomology of its hull. We give examples of explicit calculations of PV cohomology for a class of 1dimensional tilings (obtained by cutandprojection of a 2dimensional lattice).
We also study the groupoid of the transversal of the hull of such tilings and show that they can be recovered:
1) from inverse limit of simpler groupoids (which are quotients of free categories generated by finite graphs), and
2) from an inverse semi group that arises from PV cohomology.
The underslying Delone set of punctures of such tilings modelizes the atomics positions in an aperiodic solid at zero temperature. We also present a study of (classical and harmonic) vibrational waves of low energy on such solids (acoustic phonons). We establish that the energy functional (the "matrix of spring constants" which describes the vibrations of the atoms around their equilibrium positions) behaves like a Laplacian at low energy.
