چکیده

We consider several Hamiltonian systems for which the existence of Arnold's mechanism for diiusion (whiskered tori, transition ladder, etc.) has been proven. By means of Mather theory we show that the diiusion time may be bounded by a power of the homoclinic splitting.

Fast Arnold Diiusion in Systems with Three Time Scales

We consider the problem of Arnold Diiusion for nearly integrable partially isochronous Hamiltonian systems with three time scales. By means of a careful shadowing analysis, based on a variational technique, we prove that, along special directions, Arnold diiusion takes place with fast (polynomial) speed, even though the \splitting determinant" is exponentially small.

Drift and Diffusion in Phase Space

The problem of stability of the action variables (i.e. of the adiabatic invari-ants) in perturbations of completely integrable (real analytic) hamiltonian systems with more than two degrees of freedom is considered. Extending the analysis of A], we work out a general quantitative theory, from the point of view of dimensional analysis, for a priori unstable systems (i.e. systems for which the un...

Bounds on the Diiusion Constant for the Rubinstein-duke Model of Electrophoresis

We prove bounds on the diiusion constant for the Rubinstein-Duke-model by means of a variational formula. The leading term decreases quadratically with the length of the polymer chain. The coeecient of proportionality agrees with the one for the model with periodic boundary conditions. The next leading term is anomalous. Upper and lower bounds on the corresponding scaling exponent are given.

Modelling Transport in Disordered Media via Diiusion on Fractals

When viewed at an appropriate scale, a disordered medium can behave as if it is strictly less than three dimensional. As fractals typically have non-integer dimensions, they are natural models for disordered media, and diiusion on fractals can be used to model transport in disordered media. In particular, such diiusion processes can be used to obtain bounds on the fundamental solution to the he...

Error bounds in approximating n-time differentiable functions of self-adjoint operators in Hilbert spaces via a Taylor's type expansion

On utilizing the spectral representation of selfadjoint operators in Hilbert spaces, some error bounds in approximating $n$-time differentiable functions of selfadjoint operators in Hilbert Spaces via a Taylor's type expansion are given.
