Fluctuational non-equilibrium thermodynamics is formulated in terms of path integrals. The theory is presented in such a way that it will be applicable to a wide class of stochastic processes, including non-Markovian processes. In particular, we show how to construct the path-integral scheme when the noise-correlation matrix is singular, which is the case for fluctuations in non-equilibrium thermodynamics, since the continuity equation has no stochastic term associated with it. The theory is illustrated by calculating the light-scattering spectrum in fluids. Non-linear contributions to this quantity are also computed. © IWNET 2006
