NOTE Effect of Weak Brownian Motion on Gravitational Coagulation

2. FORMULATION OF THE PROBLEM

The effect of a small amount of Brownian diffusion on gravitational coagulation is numerically calculated by incorporating grav-In order to find the effect of a small amount of Brownian diffusion on gravity-induced coagulation, we need to solve the conservation equation ( 5): itational and interparticle forces (both attractive and repulsive), as well as hydrodynamic interactions. It is found that weak Brownian diffusion, the effect of which is nonlinearly coupled with gravity, [4] can act to decrease the coagulation rate.

For infinitesimal data given on the group of diffeomorphism of the circle with respect to the metric H 3=2 , the associated Brownian motion has been constructed by Malliavin (C.R. Acad. Sci.

The biased movement of Brownian particles on a #uctuating two-state periodic potential made of identical distorted ratchets is studied. The purpose is to investigate how the direction of the particle movement is related to the asymmetry of the potential. In general, distorting one of the two linear
