Stochastic Helmholtz problem and convergence in distribution

In the present paper, solvability of stochastic Helmholtz problem is investigated in class differential equations equivalent distribution. Earlier, by additional variables method was almost surely (a.s.). The study distribution allows us to significantly expand region its solvability. This due possibility using well-known methods theory processes, such as phase space transformation, absolutely continuous change measure, and random time. that paper Lagrangian structure are constructed given second order Ito measure transformation randomtime substitution. obtained results illustrated specific examples.
