Correctors for parabolic equations in a heterogeneous fibered medium. (English) Zbl 1196.35041

The authors consider the problem of correctors for the homogenization of linear parabolic equations in an \(\varepsilon\)-periodic medium made of two materials having highly contrast conductivities. The key feature of this work is the study of the effect of the initial data on the asymptotic behavior of the solution as \(\varepsilon\) tends to zero. They prove that there exists a corrector of the solution such that the remaining part is a time boundary layer which is not concentrated in the initial time.
