WebThe point is that isom. classes of line bundles correspond to cohomology classes of cocycles, so there is some ambiguity in choosing the cocycle corresponding to a fixed line bundle. In the modular forms literature, one usually imposes a further condition on the cocycles by demanding that their absolute value be of the form $ cz+d ^k$; it is ... Web1960 M.J.

We distinguish between identically singular (i.e. non-invertible anywhere) and non-identically singular cocycles. We studied the latter in Chapter 6 of our monograph [14]. This paper is concerned with the former, which Webcocycles is diophantine or rational with respect to the frequency, they are in fact reducible. This extends Eliasson’s theorem on Schrodinger cocycles to the¨ differentiable case. Mathematics Subject Classification: 37-99 1. Introduction In the paper, we consider quasi-periodic cocycles and the problem of their reducibility in the

Web§1 Description of cocycles and statements of results Perhaps the simplest dynamical system over which to carry out our construc-tion is an expanding map of the circle, so let us first discuss that case. We identify S1 ∼= R/Z. Let f : S1 be defined by fx = Nx mod 1 where N is a fixed integer ≥ 2, and let m denote the Lebesgue measure on S1. lan datenkabellan datenübertragungWebIt is well known that, in general, Lyapunov exponents can be very sensitive as functions of the cocycle. For instance, Bochi [5, 6] proved that in the space of SL(2,R)-valued continuous cocycles over an aperiodic map, if a cocycle is not hy- perbolic, then it can be approximated by cocycles with zero Lyapunov exponents. landa tegnWeb24K. 100.
