DIFFUSIVE MOTION AND RECURRENCE ON AN IDEALIZED GALTON BOARD
DIFFUSIVE MOTION AN IDEALIZED GALTON BOAR
2015/9/29
We study a mechanical model known as Galton board
{ a particle rolling on a tilted plane under gravitation and bouncing o a periodic array of rigid obstacles (pegs). This model is also
identical to...
A classical model of Brownian motion consists of a heavy molecule
submerged into a gas of light atoms in a closed container. In this work
we study a 2D version of this model, where the molecule is a...
We consider the motion of a particle in a random isotropic force field. Assuming
that the force field arises from a Poisson field in Rd, d 4, and the
initial velocity of the part...
