Random Iteration of Maps on a Cylinder and diffusive behavior.
The problem of a cylinder of mass m and radius r, with its center of mass out of the cylinder axis, rolling on an incline that makes an angle with respect to the horizontal is analyzed. The equation o...
A model of driven and decaying magnetic turbulence in a cylinder
model Driven field-aligned currents
2011/8/30
Using mean-field theory, we compute the evolution of the magnetic field in a cylinder with outer perfectly conducting boundaries, an imposed axial magnetic and electric field. The thus injected magnet...
Absolute continuity of the spectrum of the periodic Schrödinger operator in a layer and in a smooth cylinder

We consider the Schr\"odinger operator $H = -\Delta + V$ in a layer or in a $d$-dimensional cylinder. The potential $V$ is assumed to be periodic with respect to some lattice. We establish the absolu...
Strengthening constraints on Yukawa-type corrections to Newtonian gravity from measuring the Casimir force between a cylinder and a plate

We discuss possibility to obtain stronger constraints on non-Newtonian gravity from measuring
the gradient of the Casimir force between a cylinder and a plate. Exact analytical expression

2010/9/13
In the present work we propose to study the movement of a steady density of an incompressible viscous fluid in a cylindrical domain to control the external boundary. This movement with axial symmetry,...
