Аннотация:Skeleton diagram equations of turbulence theory - the Dyson equations and the equations for vertices of three types - are obtained nonperturbatively Their derivation is based on the use of an equation in functional derivatives for the characteristic functional of a hydrodynamic system described by Navier-Stokes equations in the presence of an external random force. The iterative solution of these equations reproduces the perturbation series for second moments that is usually obtained in a more complicated way and also the series for the third moments.
