Homogenization of degenerate parabolic Signorini problems with vanishing storage and oscillating surface fluxes
Hermann Douanla, Rodrigue Kenne Bogning, Erick Tetsadjio
We study the homogenization of a unilateral quasilinear parabolic problem in a periodically perforated medium. The model combines two degeneracies: the coefficient of the time deri…

Surface-to-Volume Homogenization of NonLinear Steklov Eigencouples with NonHomogeneous Orlicz Growth in Perforated Domains
Hermann Douanla, Hubert Nnang, Joel Fotso Tachago +1
We study normalized principal Steklov eigencouples on periodically perforated domains when both the bulk energy and the boundary normalization have general, possibly nonhomogeneous…

Bulk-surface spectral homogenization with indefinite mass in periodic perforated domains
Hermann DOUANLA
We study the homogenization of an elliptic eigenvalue problem in a periodically perforated domain, where the spectral parameter appears both in the equation, through a bulk density…
