Abstract.The small-amplitude homogenisation for the parabolic problem with time dependent periodic coefficients is considered. Calculating the Fourier series we obtain the explicit formula for the leading terms in the expansion of the homogenisation limit, which can be compared to the results obtained by using parabolic variant H-measures.
