Abstract: The model of laminated wave turbulence presented recently unites both types of turbulent wave systems — statistical wave turbulence (introduced by Kolmogorov and brought to the present form by numerous works of Zakharov and his scientific school since nineteen sixties) and discrete wave turbulence (developed in the works of Kartashova in nineteen nineties). The main new feature described by this model is the following: discrete effects do appear not only in the long-wave part of the spectral domain (corresponding to small wave numbers) but all through the spectra thus putting forth a novel problem — construction of fast algorithms for computations in integers of order 1012and more. In this paper we present a generic algorithm for polynomial dispersion functions and illustrate it by application to gravitational water waves and oceanic planetary waves.
