Abstract: (Springer)
From the path probability density for nonlinear stochastic processes a Lagrangean for classical field dynamics is derived. This formulation provides a convenient approach to the mode coupling equations and the renormalization group theory of critical dynamics. An application is given for the time-dependent isotropic Heisenberg ferromagnet. The dynamical exponent z=d+2η2z = \frac{{d + 2 - \eta }}{2} is derived aboveT c for all dimensionsd>2.
