title: Response theory and reduced equations of motion.
abstract: Nonlinear response theory for a relaxation experiment is used to derive classical and quantum-mechanical equations of motion for reduced distribution functions or density matrices, respectively. The classical equations are linear, but the quantum ones are not. The results are analyzed in the weak-coupling and separation-of-time-scales limits.
