Abstract
A simplified description of small-scale anisotropic turbulence is developed in the form of a set of three integrodifferential equations in one-dimensional momentum space or in the form of a set of three partial differential equations in a modified one-dimensional physical space. In the first case, the unknown functions are three coefficients in the Taylor expansion of an unstable polarization Fourier harmonic of the pulsating component of the velocity near the most unstable direction, the independent variables being time and the absolute value of the wave vector.
