The time-periodic unfolding operator and applications to parabolic homogenization
Micòl Amar, Daniele Andreucci, Dario Bellaveglia · Rendiconti Lincei Matematica e Applicazioni · 2017
We apply the method of periodic unfolding to a classical homogenization problem for a parabolic equation. With respect to previous literature, we allow for capacity-like coefficients in the diffusion equation oscillating both in space and time, with general independent scales. Our approach relies upon a generalization of the unfolding technique to the time-periodic case.
