Title: Simultaneous Brownian motion of N particles in a temperature gradient
         　 (Physica A 250 (1998) 253)

Abstract:
 A system of N Brownian particles suspended in a nonuniform heat bath
is treated as a thermodynamic system with internal degrees of freedom,
in this case their velocities and coordinates. Applying the scheme of
nonequilibrium thermodynamics, one then easily obtains the Fokker-Planck
equation for simultaneous Brownian motion of N particles in a temperature
gradient. This equation accounts for couplings in the motion as a result
of hydrodynamic interactions between particles.
