Variational principle for stochastic wave and density equations.
We develop a stochastic generalization of the McLachlan variational principle and show that it can be used to derive known stochastic wave equations. We then use it to obtain an exact probability preserving stochastic density decomposition for vibrational dynamics problems with pairwise interaction.
