ABSTRACT
Despite of its success in prediction of the second-order moments of quadratic nonlinear dynamical systems the formulation of the direct-interaction approximation (DIA), which was originally invented by Kraichnan (1959), has been unclear and sometimes misunderstood. A new convincing formulation of DIA is presented here that is based on sparseness of nonlinear couplings and on largeness of the system size. © 2000 American Institute of Physics.
