abstract:
For the multi-frequency system of the differential equations the right-hand
sides of which are represented by a multiple Fourier series with slowly varying
coefficients, the conditions are obtained under which there exists the
transformation with the coefficients of similar structure leading this system to
a system with slowly varying right-hand sides.
