Algebraic approach towards conductivity in ergodic media [PDF]

, 2013
This thesis is about an operator algebraic approach towards the derivation of the electrical conductivity in disordered solid states based on the theory of quantum many-particle systems. Such an approach is of interest since it allows for the description

A parametrised version of Moser's modifying terms theorem [PDF]

A sharpened version of Moser's `modifying terms' KAM theorem is derived, and it is shown how this theorem can be used to investigate the persistence of invariant tori in general situations, including those where some of the Floquet exponents of the ...

Random Dynamics and Finance: Constructing Implied Binomial Trees from a Predetermined Stationary Den [PDF]

We introduce a general binomial model for asset prices based on the concept of random maps. The asymptotic stationary distribution for such model is studied using techniques from dynamical systems.

Nonlinearity and Temporal Dependence [PDF]

Nonlinearities in the drift and diffusion coefficients influence temporal dependence in scalar diffusion models. We study this link using two notions of temporal dependence: beta-mixing and rho-mixing.
