Full textThis thesis is dedicated to the study of reducibility and almost reducibility of quasi-periodic cocycles, which are the fundamental solutions of linear differential Systems with quasi-periodic coefficients. A notion of conjugation, in the sense of cocycles, by a quasi-periodic transformation, is introduced; quantities which are invariant by this type of conjugation are called dynamical invariants. When a cocycle is reducible, it is possible to have a good knowledge of its dynamical invariants, such as Lyapunov exponents which indicate the asymptotic behaviour of the solutions of the System, and in dimension 2, the rotation number which gives their mean rotation around the origin. Almost reducibility enables one to have quite a good control on these invariants on an arbitrarily long time. One introduces the notion of reducibility of a cocycle in a linear Lie group G modulo 1 or 2, as the possibility of reducing the cocycle by means of a transformation with values in G and which is defined either on the torus, or on a covering of the torus; it is then shown by a geometric argument that a cocycle with values in G which is reducible in the group of invertible matrices is reducible in G modulo 1 if G is complex and modulo 2 if G is real. The second part concerns the problem of almost reducibility, that is, whether it is possible to conjugate a cocycle to another one which is arbitrarily close to a reducible cocycle, in some fixed topology. We state and prove a perturbative result of almost reducibility of analytic cocycles with diophantine frequency which are close to a constant cocycle and take their values in the symplectic group. Almost reducibility is obtained in the space of analytic functions on a fixed neighbourhood of the torus, with only one period doubling, through a KAM-type method estimating how often small divisors, or resonances, appear. Quasi-density in this topology of reducible cocycles near a constant comes as a corollary

Full textIn this thesis we mainly generalize two theorems from Mackaay-Picken and Picken (2002, 2004). In the first paper, Mackaay and Picken show that there is a bijective correspondence between Deligne 2-classes $xi in check{H}^2(M,mathcal{D}^2)$ and holonomy maps from the second thin-homotopy group $pi_2^2(M)$ to $U(1)$. In the second one, a generalization of this theorem to manifolds with boundaries is given: Picken shows that there is a bijection between Deligne 2-cocycles and a certain variant of 2-dimensional topological quantum field theories. In this thesis we show that these two theorems hold in every dimension. We consider first the holonomy case, and by using simplicial methods we can prove that the group of smooth Deligne $d$-classes is isomorphic to the group of smooth holonomy maps from the $d^{th}$ thin-homotopy group $pi_d^d(M)$ to $U(1)$, if $M$ is $(d-1)$-connected. We contrast this with a result of Gajer (1999). Gajer showed that Deligne $d$-classes can be reconstructed by a different class of holonomy maps, which not only include holonomies along spheres, but also along general $d$-manifolds in $M$. This approach does not require the manifold $M$ to be $(d-1)$-connected. We show that in the case of flat Deligne $d$-classes, our result differs from Gajers, if $M$ is not $(d-1)$-connected, but only $(d-2)$-connected. Stiefel manifolds do have this property, and if one applies our theorem to these and compare the result with that of Gajers theorem, it is revealed that our theorem reconstructs too many Deligne classes. This means, that our reconstruction theorem cannot live without the extra assumption on the manifold $M$, that is our reconstruction needs less informations about the holonomy of $d$-manifolds in $M$ at the price of assuming $M$ to be $(d-1)$-connected. We continue to show, that also the second theorem can be generalized: By introducing the concept of Picken-type topological quantum field theory in arbitrary dimensions, we can show that every Deligne $d$-cocycle induces such a $d$-dimensional field theory with two special properties, namely thin-invariance and smoothness. We show that any $d$-dimensional topological quantum field theory with these two properties gives rise to a Deligne $d$-cocycle and verify that this construction is surjective and injective, that is both groups are isomorphic.
