Our main result is a Smoluchowski equation valid for moderate to high damping constants. We derive that equation by perturbative solution of the Langevin equation and using functional derivative techniques.5 p.application/pdfeng(c) The American Physical Society, 1990Fluctuacions (Física)Mecànica estadísticaMoviment browniàFluctuations (Physics)Statistical mechanicsBrownian movementsBrownian motion of multidimensional systems in nonpotential velocity-dependent fields of forceinfo:eu-repo/semantics/article33518info:eu-repo/semantics/openAccess
